I was sort of wondering if it was the 360 actually when I looked at the two first images. When I saw the third, it became clear it was good ol PS2...
The two first shots do look very nice, particulary for PS2 I think. The third looks a little skanky perhaps, but it's mostly the fault of the fog, which accentuates jaggies and other rendering imperfections. Fog is hard to do well.
