@XISMZERO: People have already picked the entire trailer apart and looked at the official artwork so far, and lots of people are pointing out that some of the shadows in the background look like Frank West and Dante.
Frank West would not be surprising, considering he's in Tatsunoko vs. Capcom.
In fact, since the visual style is probably going to be similar, I'm expecting pretty much all Capcom characters from TvC to make it into MvC3.
Zero has to be in there, or I'll go ballistic.
And I'd much prefer Megaman X over any other form of Megaman.
Any other characters from the MM universe are extremely welcome (Sigma please! And maybe Vile).
We're already getting Chris Redfield, but Leon would be nice too.
I'm fully expecting Wesker too though, and maybe the return of Jill. Sheva would make sense too, I guess.
A gazillion Awesome Points to Capcom if they throw in RE4's merchant.
And hey, considering that Capcom did a shitload of Disney games and Marvel now belongs to that very same company, maybe we can expect Uncle Scrooge, Chip 'n' Dale and Darkwing Duck as well
