I agree about keeping it on Xbox. But if they ever decide to release it on PC, I wouldnt be too upset. The people at Gearbox have made a great port for Halo, and kept the single player experience the same, just upped the multiplayer with so much new stuff, such as new maps, an editor, a few new weapons, new vehicles, etc. And made it great for online multiplayer.
If oddworld decides to make a pc version of any of the new games, either they should do it, or work closely with the company the way bungie did with Gearbox.
