Just some random though about 360 and PS3 hardware. In both case the processors were mainly designed base on the IBM PowerPC chips. Sounds a bell anyone? Yep it's the same architecture that once equipped the Mac. So we are all playing on Mac! Sort of...
The biggest change will come from better GPU and both NVIDIA and AMD are working hard on better integration between the GPU and the CPU. It's next big thing.
IMO, their CPU are sub-optimal in both cases, with Cell being a bit weaker in brute force, but better designed for video game (vectorization mainly) so it even out. Then on the GPU side, PS3 is weaker, with half the memory and slower clock than the ATI card equipping the XBOX 360. On a technological side, the PS3 is more advance and represent a better integration. The 360 is like a traditional PC.
