[quote name='goomba478']Good question! Also guys if you owned the PS3 and the Xbox 360 which version would you recommend buying? I just got my PS3 today so I'm stuck. Let me know what you think ^_^ Either way I respect your opinion.[/quote]
Graphically and content-wise, they are supposedly the same across platforms. However, the PS3 version forces you to install the game to your hard drive (there is no option to bypass it). The process apparently takes about 20-25 min, but eliminates in-game load times. It may be enough to turn some away, but it sounds to me like it could be worth it - so I'm going with that. My 360 died on me anyways...
I guess the biggest issue when choosing between the 360 and PS3 versions is controller preference. Just go with what you are most comfortable with.

About the OP's request, the only deal so far is using the 10% off coupon when you get it at GS. I'm sure there will be better deals as the release approaches.
