From: alex91093 We are still getting the ps2 version of the game. That is what hes talking about.
We are getting a version based on the PS2/PC version (and this is actually speculation from users, not a confirmation from Capcom).
However, it is a fact that Capcom is updating the game (graphics, trophies/achievements) and including all the past bonuses, so we know for a fact that it's not going to be a straight port. If it is indeed truly the case that the 360/PS3 version is based on the PS2/PC version, then they probably chose that version due it being the easiest to port technically. That's all.
