We don't know if this is 360 footage but if it is then looks pretty amazing.

Crysis 2 was far too ambitious on current gen with dodgy AA, pop ins and crappy frame rates. Killzone 2 & especially 3 are still FPS technical accomplishment kings overall though one could argue Halo 4 is better looking in some ways but that's mostly due to art direction.
