Yes yes Marvel vs Capcom 2 is finally out on XBLA for the low price of 1200 xbux.
It comes out on the PSN on Aug 12th for $15!
My impressions:
Great! Netcode is pretty good. 6 player lobbies, ranked matches, all the basic stuff you'd want from a fighting game. Everything comes unlocked so you don't have to spend hours in singleplayer trying to get all the characters or colours.
Basically if you like Marvel vs Capcom 2 then there's no reason not to get this.
Though so far the only problem I've seen is the character select screen lags a little online but after that it's great.
my gt is Overbite, let me take you for a ride.
