I'll probably get this game on both platforms (and maybe PC too-- is it coming out on Steam like Puzzle Fighter did?) if I can figure out a way to buy the game from the U.S. PSN, but 360 is going to be where it's at, simply for the sheer size of the community alone. This game is being made with online play in mind, and there's no question that XBLA is place to be for that.
