Crysis requirements having nothing to do with the power of the graphics elements of the consoles or at least what Deimier said shouldn't be taken as outright processing power...
Its just resources...
On a PC you have dedicated graphics and system memory... At least 768MB in total.
On an Xbox you have a max 512MB total and that's shared for everything... So you either have smaller maps, lower detail or less objects in the scene...
Think about this logically, Crysis will work on GF7. PS3 has GF7, 360 has an even more advanced GPU both capable of DX9.0c effects. The very same DX9 that's a requirement on the PC
