@MrGerbz: I believe it's quite hard to bring up the fps once the game is done. It would actually make the game play faster, unless you re-arrange the animations, which wouldn't be worth it. At this point, 30fps is ideal, since it's how the game was intended to be.
@The_Saint: I'm in the same boat, except I JUST bought my 360, so i need to buy games for it. As for your case, i think 360 as well since, unfortunately, they will probably have more DLC down the line than on PS3. Let's pray it's not the case, though. #modernwarfare2
@a-xxv: That's actually a very good idea... Not only could we cross-game chat with it, but we can also use it for ... ya know, what it was created for. Free calls!
I support your idea, good sir.
