To be honest, It's not something you'll notice, On release nobody did, It was only after some indepth analysis did it come to light.
If you are going for a version of the game, it still stands, that either version of the game is fantastic. And there's only slight differences between the 2.
aa improved and pop-ins being reduced on the PS3, But that's not saying the pop-ins are totally noticable on the 360. They hardly are.
Downloadable content is a plus for the 360 version, But it's not even out yet.
The 640 vs 720 thing is just fanboy fodder to be honest.
Well said that man !
I have got to admit though that the PS3 version is blurry (haven't seen the 360 to compare yet). I'm going to turn up the sharpness on my HDTV tonight, as a few have suggested, to get an overall, albeit artifical, sharpness.
