I'm not sure if this was covered in Wind's video but that is the guy I heard this from so it may very well be.
Basically the selling point of this game to DBZ fans and people who bought UT is that there are supposed to be 6 or 8 new characters 2 of which have never been in a DBZ game before. I haven't heard if this game will have character creation or not but if they add a female option I'll be sooooooo pissed...

So I just decided to recheck up on this game. Including separate forms as different characters this game apparently has a roster of 50+ including none other than:

Super Saiyan Bardock...

Apparently Episode of Bardock will also be included on the disc.

I the game at a friend's house. I ended up humping everything in the room.
