While UT2007 coming to the 360 is a good thing for the console itself, I really have no interest for it, on any console. The game was and is made to be played on a PC, it just doesn't suit a controller well. PC->Console FPS ports are generally sub par, since they are designed to be played on a PC, same condition applies to Console->PC FPS ports (we all remember Halo on the PC...) Games are tailored to the main system on which it will be played. UT is just a reflex game, very faced paced, and I don't think those kinds of FPS's meld well with consoles.
That's just IMO of course.
