Both FUNimation and TOEI have confirmed that there is no such character as Super Saiya-jin 5 Goku, and that there is no new Dragonball series in production (yes, that includes the often rumored about Dragonball AF). It has also been confirmed that Dragonball AF and, consequently, the image of Super Saiya-jin 5 Goku is part of a doshinji (a Japanese fan-drawn manga). So, please, get over this whole DBAF/SSj5 Goku thing.
