I'm speculating here, but if you're asking this question to help you decide which console to buy, then go for the Xbox. Most games now are released on both consoles and are alot better on the Xbox due to the superior hardware. As regards to exclusiveness I believe that San Andreas will be out on the Xbox next year (I think Sony have the Christmas rights. Correct me if i'm wrong). And Microsoft exclusive games such as Project Gotham and Halo are amazing. Juxtaposing games such as Fifa and Vice City for the two platforms reveals a huge difference in quality, with reduced loading time and better graphics on the Xbox. The Xbox pads are better as well.
