Saw an ad in Offical Xbox Magazine for Unreal 2, and it showed a few XMP screen shots, with the Xbox live logo on the ad. So that means XMP support for the Xbox too! It isnt going to be as good as the PC version of course, but I wouldnt mind picking up the Xbox version of Unreal 2 for XMP on there. Atleast you'll be able to play with a nice frame rate and good graphics.
