It looks gorgeous and will no doubt be a solid game, but my interest in it depends entirely on the cast. Part of me wishes they would bring over whoever they can bring over from Ultra 4 and the other part of me wishes they would go nuts and swap out most of the cast. In a perfect world though, they'd have a gazillion zenny and would be able to bring over every Street Fighter character (maybe a few Darkstalkers? wink wink nudge-fucking-nudge) ever because that would be insane.
I would honestly love if they pulled a 3rd Strike move on this. Just have a couple of the main-stays like Ryu and Chun and then just go totally nuts on the rest of the crew. All new dudes. It would actually be kinda fitting since 4 at this point has like everybody.
