Well like I said, this is video game. GT only sucks for the story, but not the character. Majority of fans always welcome GT characters in a game. Obviously they will not add all of it, just an important one, like you said SS4 Goku. That goes for Super as well, is not like they gonna add all new characters from Super. Although for win win situation, I can see that they can add GT characters via DLC. I also want the original DB characters too. The likes of King Piccolo, Tambourine and Devilman should get the love they deserve after Tenkaichi 3.
