I'm still surprised they went with x86 jaja
Is all this info mostly xbox Next? Main question being, by the rumors, are both MS and Sony using Jaguar cores?
X86 is by far the best possible choice, as you have a zero learning curve.
Using "Standard" GPU will also facilitate coding & porting, having a "fixed numbers of cores" and "less layers (API)" will make everything even easier. (1 core for IA, 1 core for Physics, 1 core for Kinect, etc etc).
I'm surprised they didn't go that route sooner.
