Its probably not going to happen for money reasons, but here is my case of why i think it should.
1 XBOX will hold the game back. The PS3 can go alot further than XBOX in terms of how much more can be put in the game because the PS3 is more advanced (I guess releasing the console later payed off in the long run).

2 PS3 is the present and the future of this generation of consoles. Many people are ditching the XBOX for a PS3. (at least who I have talked to) and the ps3 is predicted to pass the 360 in sales sometime in the next year.
Do you agree? Disagree? Any other reasons you can add to my list?
Also, 360 fanboys, please don't get all pissy about this, it's just my opinion and it probably won't happen anyway.
