I still think it's too early to judge the graphics of Crysis 2 on consoles as Crytek seem to have been pretty busy developing tools and upgrading the engine rather than developing the game. The game's assets are probably still in heavy production and I highly doubt many completed assets are shown in those pics. It's similar to how GoW3 got flak when showing unpolished screens or the E3 demo. The difference between those shots and the final build were quite immense.

The tech demo Barozi linked shows a tech demo utilizing many finished assets from Crysis 1 which is why it looks so good. The pics in the OP were taken from the tech demo they shown at GDC ( http://www.gametrailers.com/video/gdc-10-crysis-2/64317 ) which most likely uses a lot of unfinished assets and placeholders. I don't think we can judge the visual fidelity until the assets are more complete. From what that tech demo shows though, the physics and particle effects are looking really good which was the sole purpose of that tech demo - to showcase the abilities of the engine and not demoing a final product.
