I'll be picking this up shortly.
Found something VERY interesting on the Beyond3D Forums. Probably deserves it's own thread really. Apparently the PS3 version runs at a res of 620 to 630P with NO AA and the 360 is running at 720P w/ 2xAA. There's always something when peeps say a game is better on the PS3. Then the real facts come out.
