Well, the pics I've seen of GT5 look amazing. But, I'm not buying a PS3 just for the privelage of playing it.
And, I agree with Magnum that any high-end PC will display NFS:Shift better than the 360 will. Although, even on the 360, Shift looked excellent. I just hated the gameplay.
What resolution does the PS3 play games at compared to the 360? Just curious.
I have noticed an ocassional hiccup (lag) while playing Forza3 when something like an Achievement notice pops up. It's irritating but not a show-stopper.
I've got a new PC on the way, I'll keep NFS:Shift in mind for the mods. If they can fix the awful AI and questionable physics it might be worth looking into again. But I can pretty much satisfy all my racing needs on the PC with rFactor, even though it's starting to show it's age.
