There's no doubt about it, even though the Xbox 360 comes out a few months before the PS3, the PS3 will kick its ass all the way back to the Microsoft offices in Seattle.
I was reading an article yesterday about the Xbox 360, and they mentioned that M$ are still losing money on the Xbox. They haven't made any money at all!! Surely not?!
Also the NVidia chip allows the PS3 to be 128 bit, instead of the regular 32 bit. Now that is the crazy part.
