I got Capcom vs SNK 2 EO for Xbox yesterday and I spent a good few hours last night with it. First of all, Xbox controller sucks for fighting games; the d-pad feels weird and the button layout is just plain horrible. Gameplay wise, the Xbox version isn't much different from the PS2 version except that they took out roll cancel and added super cancels in P-groove. Graphics are exactly the same as the PS2 version. As for sound, almost every match either the music or the sound effects would cut off for no reason, I don't know if that has anything to do with the fact that my TV is monoaural; I've never had that type of problem with the PS2 version. I haven't played it online yet, I'll wait for my arcade stick to arrive, I don't want to get my ass kicked online because of a bad controller. Overall, I'd say the only good thing about the Xbox version is online play, other than that the PS2 version is better. However, I'll have to spend more time with the game before getting to final conclusions about the game.
