SSF4AEv2012 and UMvC3 guaranteed.
It's actually possible that Scull Girls will beat out BlazBlue. Even with the update I really don't see that game drawing in much numbers.
MK I think will stick around. The game does well enough IMO to stay.
SC5 will be in without a doubt. The added new features gives it a ton of hype and makes it seem like a new game. The game has the potential to do far better than any SC has in the past and stick around as a very relevant game until SC6, but it's going to depend on how the community handles it(which I am worried about). But for Evo 2012, there really is no question.
T6 is gone. No offense to fans or anything but it really shouldn't have even been at Evo2011. I think the recent Capcom and Namco affiliation is the only reason T6 was there.
SFxT will be there. Despite the gem dilemma the game really has nothing to worry about. I honestly think people are simply overreacting to the crisis. The fact that you can select no gems pretty much handles the problem. Although I think the game can be played with gems and still be very successful. Capcom needs to have a standard set of gems that naturally comes with the game and then that will set a basis for tornaments.
I honestly think FG players(from all FG communities) can be so dramatic and bitchy about things. Similar to the way some(including myself) reacted to CE and BE in SC5 saying "oh they're trying to make it SF4". Sometimes tournament players just need to calm down and think things through before throwing a temper tantrum. I actually think SFxT would have had a more secure future if people didn't over react to gems.
