After reading this entire thread....
first of all.. none of you know whether or not GRAN TURISMO 5 WILL RUN AT 1080P or at a resolution similar to GT5 PROLOGUE which did run at 1280X1080 resolution. Latest in game screens show a 1920X1080 resolution.. I say its more than likely the game will be native 1080p. The game also runs at a constant 60fps, and will feature 3D/PSMOVE/HEAD TRACKING technology.
So before all of you claim to know everything, GT5 has not been confirmed to run at 1280X1080 or native 1080p..
On another note, for those saying "only PSN games or those that require little graphics detail run at native 1080p" well then I guess this will prove you wrong:
Tekken 5 Dark Ressurection (screenshot) = 1920x1080 (no AA), not always?

I believe GOD OF WAR III could have been native 1080p resolution, since the game runs at average around 40-45fps.. it would have likely dropped to 25-30fps, but still could have run at 1080p resolution..
