sony have done everything in there power to make PS3 development as easy as possible, it has just taken a while, I agree with what crytek say say, coming to the party late has definitely worked in their favour with regards to the ps3.
here's a thought: ps3 gpu < 360 gpu, ps3 cpu > 360 cpu, gpu = for graphics, cpu = for game mechanics, most games: 360 > ps3, crysis: ps3 > 360, hence, crysis has more advanced game mechanics than most other games! == good game!!!
it must be! maths don't lie!! (although chances are the cell is used mainly as an auxiliary GPU to aid the PS3's GPU, that's how it usually works.)
