I don't usually care about these comparisons, but MAN!!! is that resolution a lot lower. These guys really are left looking a bit silly when taking into account their pre-release PS3 statements.
What engine is this game using? I am guessing a custom made one. Now, this is speculation, but maybe their engine is not so hot when it comes to scene ordering and throwing out invisible areas and they are dealing with bad overdraw. In pixel heavy situations, the PS3 can struggle with fill-rate and maybe that is causing the problem here. The 360 with it's stream processor like architecture would handle "bad" engines better I think (I am waiting for the backlash for that statement).
Quality engines made by Epic and ID shouldn't be underestimated.
