*I get most of my info from other sites(such as The Buffy Cross & Stake and Fellow Tweakos United), or just from around. I can't say whether or not all of it, some of it, or any of it is true. Even if some isn't, it's still fun to read and speculate. NOTE: the newest rumors and such are in bold text.
-David Boreanaz(Angel) and Charisma Carpenter(Cordelia) ARE staying on 'Buffy' for the rest of the season(yay!)
-For those of you few people that haven't yet heard, David is heading for L.A. to do a spin-off of 'Buffy' entitled 'Angel' that'll start in fall/99. Charisma'll be joining him, possibly helping out every once in a while. Whistler'll be on 'Angel' as well, for those of you that liked the little 'not a bad guy' demon. Some of the characters from each show *will* do guest appearences on the other show(and there'll be occasional cross-overs between the two shows). 'Angel' will be for older viewers(He'll "save souls and punish demons"). Some say it'll be a long-lived series, while others say that it's only gonna be a one year thing, and that David'll be headed back to 'Buffy' after that.
-Possible cast of 'Angel': Angel(for obvious reasons), Cordy(she'll be his side-kick), Whistler(though he may not be played by Max Perlich, who played him in 'Becoming'), Faith(I don't know why), Amy the witch(again, I'm not sure why), Spike and Drusilla(because of their history with the ensouled vamp).
-It'll be on L.A.'s Hellmouth.
-Cordy'll persue acting there.
-Angel may have a recurring nemesis(possibly in the form of a law firm) that knows who and what he is.
-Angel will have to deal with inner and outer demons, which means there may be flashbacks of his past.
-Also, Cordy will *not* be a vampire.
-Angel won't date anyone, and will always have feelings for Buffy(and yet she *will* date. Is anyone else seeing something weird about this?).
-Oz may cheat(or have cheated) on Willow.
-When Cordy moves to L.A. she may become unpopular, and be unable to make friends.
-Joyce may be pregnant.
-Buffy and Willow'll be roommates in college.
-Oz leaves Sunnydale to persue a career in music with the Dingoes.
-Willow and Xander start dating.
-A possible beau for Buffy is Riley Finn, a guy with a secret life.
-A pretty solid rumour flying around is that Angel's curse was made permanent in 'Becoming', but no one knows it yet.
-Whistler may take Angel's place next season as the guy who warns the gang about danger, after Angel leaves of course.
-Jerry O'Connell (Sliders) may guest star in season 4 as Pike, Buffy's former flame (from the movie).
-When Angel comes back to visit Buffy (in season 4), they get pretty hot and heavy.
-Sometime later on, Oz gets killed...and Willow suspects Buffy of doing it.
-Okay, there have been rumours flying around about (gag!) Cordelia and Angel hooking up. It sounds like a Buffy nightmare but actually it's close to reality. Rumor is the unlikely duo locks lips and leaves Sunnydale High School in the dust. Poor Buffy! Cordelia is apparently headed for leading-lady status in the spin-off, "Angel". Is this making anyone else out there sick?
-There may be a movie based on the series(same characters, and probably the same actors playing the characters). The script is being started, and it may happen sometime in 1999(don't hold your breath).
-Angel's not the only ensouled vampire.
-Willow's mom'll be back, and Cordy's mom may be killed(creating an exit to L.A. for Cordy).
-The Watcher's Council tries to recruit Willow.
-A future ep'll show the gang *in* the future, and show Buffy as a married, working girl.
-The Mayor'll throw a re-election party, with many interesting guests.
-Angel'll be in the first few eps of BtVS, 4th season.
-According to Joss(Whedon), Spike *won't* be back for a while yet. They have some "fun" planned for when he *does* return, however.
-Faith may be turned into a vamp.
-Faith's dead Watcher may have been her mom.
-In a future ep, a character will have the ability to spontaneously combust.
-They might 'kill' Principal Snyder off. Actually, he'll become a demon of some sort(a zombie seems more likely than a vampire). His replacement may be even worse!
-Nick's twin, Kelly, may guest star in an ep(probably in an 'evil twin/clone' type scenario).
-Amy's witch mom escapes from the trophy she was imprisoned in.
-Xander'll confess to Buffy that he lied when he told her that Willow said to kick Angel's ass, and'll tell her the truth. He may also confess it to Angel.
-Xander and Angel'll bury their differences, and maybe even become friends.
-Buffy'll forgive Xander for the lie because he saves he life.
-Buffy'll get a new boyfriend next season.
-Willow and Oz may take their relationship further, with extra precautions.
-Snyder may not be a *bad* demon.
-Jamie Kennedy may appear on 'Buffy' next season(possibly as a vamp or as her boyfriend).
EARSHOT
Airs sometime later, on (possibly in June).
-Buffy becomes 'infected' with an aspect or characteristic of a demon she kills. That aspect turns out to be telepathy.
-Buffy's telepathic power may nearly make her literally crazy.
-Buffy's friends'll be there to help her throught this, partly because they don't want her to go crazy, and partly because they don't want her to read their thoughts.
-Larry'll resurface in this ep after becoming a zombie in 'Dead Man's Party', and Buffy'll find out his secret(that he's gay).
-A nearly fatal run in with a pair of oozy, mouthless demons leaves Buffy with telepathy.
-With her powers, she unearths a potential mass murder plan at the high school, and her and the gang set off to find the would-be murderer and thwart the plan.
-Meanwhile to all of this, Angel endeavors to keep Buffy from falling into telepathy-induced maddness.
Part 1 airs May 18(17 in Canada) and Part 2 airs May 25(24 in Canada)
(Most of this info is made up of rumors, and might not all be true)
-Cordy and Xander admit their love for eech other before peacefully going their seperate ways (I accidently had it down as a spoiler for 'The Prom').
-The Mayor becomes a snake-like demon during his commencement speech.
-The season finale may be a (grrr!) cliff-hanger (those are sooo annoying...).
-The season ends with a bang (literally). The school apparently gets blown up at the end of the episode.
-This may or *may not* be Angel and Cordy's last ep, some say they'll be in the first 4 eps of season 4.
-The First Evil *may* make a return(but this is just a rumor so far).
-Somebody(but not a main character) may die.
-This is the day of the Mayor's ascension, and the graduation day for Sunnydale High.
-This episode is supposed to be 'shocking'. Something that's all sorta hush-hush is gonna happen that'll shock everyone!
-Buffy doesn't kill Faith, but she does hurt her badly, and puts her into a coma. Faith will be left in a position where she can die or not and that gives Eliza the opportunity to come back or not.
-Against his better judgment, Buffy forces Angel to drink her blood when she is the only Slayer left for him to drink from. She persuades him by hitting him repeatedly until the demon can't be held back.
-Angel takes enough of her blood to restore his strength, but it's also enough to send Buffy into unconsiouness.
-At the hospital, the doctor's suspect that the two were doing drugs, when Angel's super strength mixed with worry for Buffy's life leads to him breaking a door frame with his bare hand.
-When Buffy quits working for the Watcher's Council, Wesley goes back to England.
-Snyder, Larry, Harmony, Jonathan and Percy are all expected to die.
-Larry and Jonathan help set up a series of bombs in the library to destroy the school.
-During graduation, while the Mayor is making a speech to the students, an eclipse takes place, vampires come running out from everywhere and at Buffy's command, all of the Sunnydale students pull out weapons of all kinds ready to take on the force of vampires.
-Meanwhile, Buffy lures the Mayor (using his love and appreciation for Faith as bait) away into the library where he is trapped. Buffy escapes just before the building is blown up.
-The Mayor attempts to kill Buffy when he finds out what she did to Faith, but Angel stops him and the two have a very cool fight in the hospital.
-Buffy'll actually have a social life in season 4. According to Joss "she's been through the wringer", and deserves it. She'll date, go out (to clubs and parties and such I guess), have more friends, and that sort of thing.
-Season 4 cast: Buffy, Willow, Xander, Oz, Giles, Spike and Dru.
-Spike'll be pretty much *forced* into helping Buffy and co., but won't be all soul-having. He'll still be the same bad vamp he's always been.
-Buffy and Angel's relationship will come to a peaceful, but moving and touching end.
-A third friend may come between Willow and Buffy's friendship. It isn't known if it'll endure. All Alyson's saying is: "Remember last year when Angel became evil? You know how it basically changed the whole show? Well, there's another thing like that coming up, but I can't give it away because the producers will kill me off."
-Spike AND Dru'll be regulars on Season 4. Neither will be back anytime this season though.
