Anything claiming to be a screenshot of a PS3 game in action is making quite a claim, since just TWO DAYS AGO Ken Kutaragi announced that final Dev Kits wont be shipped until June. So those graphics probably are on par with current PC, because it's running on a current PC and being developed on a current PC. I find it highly unlikely, and very improbable that those images are of the PS3 version.

Just my two cents.
