I agree the game looked pretty good on PS3, but some of those shots are somewhat misleading. All of those but two or three were taken off screen it seems. The game had some bad AA (that was dynamic), and the motion blur hardly ever was that perfect. The textures were also pretty bad on everything that wasn't a character.
[Make sure to open these in their own tab or expand them, the quote's resizing makes them look much better]
The game looked good on PS3, but the improved resolution and framerate will definitely make it MUCH better.
