Just purely out of curiosity, but is there any reason you are looking specifically for a 1080p title?

All you need to know in detail is here..

The bottom line is, all 360 games can 'output' at 1080p, whether they 'render' at that or not, but only 'some' PS3 games will output at 1080p even if they render at a lower resolution.
The list from that link shows the native resolution of just about all games on both consoles including PSN/XBLA.. It also describes the intricacies of how the scaling to 1080p is done (if required).
I disagree. Gran Turismo 5 looks amazing at 1080p by far the best looking racer compared to any 720p/1080p title out there.
I think you will find it does run in 1920x1080 in game.
in fairness I'd hardly class 720p as "foggy"

Compared to the TV's that I've had since they are way sharper and crisper than that bloody thing was.I like crispness and not a foggy blur.

I'm pretty sure the 360 doesn't natively do 1080i/p, it uses an onboard scaler to reach those resolutions and it isn't particulary good either.
I displayed this HD Test Chart on the 360 in 1080i fullscreen in an attempt to get 1:1 pixel mapping.
Below is the uncompressed image that was captured from HDMI (exact digital copy of the signal so no loss in quality).
The 1 pixel areas have been replaced by a moire pattern, it hasn't retained 1:1 pixel mapping, and it's generally more blurry.
Gran Turismo is 1280x1080, it's stupid to call it 1080P.
It would be like saying 320x720 is still 720P.
No it's a game that upscales

It upscales to 1080p, much like GTA4 scales to 720p, when infact it's closer to 600 i believeGran Turismo is 1280x1080, it's stupid to call it 1080P.

The name is taken from the vertical resolution. As its 1280x1080 progressive, its 1080p. Pretty obvious.
