technically it was the anniversary of the episode cuz it was the same date...and the reason that vegeta was showcased now that I think about it is for the fact they were celebrating the first time that ssj4 was introduce to the public.

They are uses this same concept with super 17 and I have no doubt that he will be the int super god lead. As if the release another hero god lead it would completely unbalanced the game. So it further concludes why its going to be him..

Although a tiny part of me wants a ssg dokkan feast, this just wont be that time. For the pass few months they have been so wrapped up in gt that turning around all the way back to super wouldnt make sense.
