X-Box 360

One of the new next-gen consoles. This one is the one made by microsoft, and it does look pretty awesome. And although 2 of those guys before believe otherwise, you can't say it will be more awesome than the PS3 and the rev when you don't know anything about what either will be like at release.

Want to play X-box 360?
