New XBox with 3x PPC G5

You forgot that Microsoft makes VirtualPC, and could run x86 (read, legacy XBox) software on PPC (read, X-box2 if done in PPC) easily.

I play a few PC games using VirtualPC on Mac OS X on Mac-on-Linux on my Pegasos, and it's acceptable.  

There's also the other bit folk forget, IBM has developed a hybred PPC/x86 chip before, the 615.

The lack of nVidia is more likely going to be limiting than the lack of x86.
