Here's the big question- would CM work on a console?
User wise, yes. If people can play RTS games the ease of use of the CM engine would be simple to use. Whether a console player could be bothered to play is another question (mabye if they dumped the real world vechiles and put in SF/Fantasy units you could. What the hell is a Sherman SHSS for anyway?).
Program wise? The big thing MS is pushing is that it'll be VERY easy for PC games to port to it (though it's what 20Meg Hard Drive won't be much use, apart from patching. You won't see Deus Ex on there anytime soon). And no way could it handle Falcon 4's patching! But my guess it'll work with all PC addone's, like Force Feedback Joysticks and keyboards and such (once MS makes them for thier own special USB port that gee, no one else can use).
Mabye CM IV will run on it. (Persoanlly I hope not. If MS sees how good this game is, the'll buy it and make it so it's exclusive to the xbox. Budgie anyone?)
