I think Evo 2011 is going to have done good things for MK 9 after those final matches.
MVC3 will be just a demonstration on what true game brokeness really is.
And SSF IV AE....well it's Street Fighter, the king of fighting games (whether you like the series or not), but if its a Yun sausage fest then it could turn out to be boring. Ono admitted that he deliberately made Yun and Yang broken and it totally killed the AE community. Only now is he going to release a free patch to fix them, so his broken characters idea totally backfired on him.
Yes, I think MK 9 at Evo was definitely in the right place, at the right time. MK 9 had massive variety, while all Tekken was, was a giant Bob/Law fightfest.
