Compared to PCs, the XBox 360 and PS3 were never even close to the performance of the top of the line PC; as time goes on and Moore's Law continues to push bleeding edge PC hardware to new heights, the PS3 and XBox 360 look more and more obsolete in comparison.
This isn't to say that the PS3 or XBox 360 are weak, in reality they are very powerful systems for their price. The problem is that at the bleeding edge (where Crysis lives) PCs are (at least) 4 times as powerful as the PS3 or XBox 360 and it is silly to expect that they can produce the same kind of results in physics or graphics without sacrificing something.
