I've already imported the X-Box version from Japan, and of course it was awesome. I'm pre-ordering the US version too, because Namco has said they're adding some features for the American release. The only additions I could find were Rock and Hwang (possibly to replace Beserker and Assassin, which is a half-ass "addition"). Anyone know of any others? Stages, Characters, Modes, technical stuff (i.e. the 4:3 720p wierdness)?
