They'll probably go X86 to dispense with any problems. An accurate mouse like interface deserves binary compatibility with the PC market, right? Add native video decoding, reasonable quantities of ram and a reasonable size chassis, they can then work their magic once again making relatively basic hardware sing to entertain a very wide spectrum of the populace.
I would no be surprised if the next generation console was:
4x 2gbit/4gbit DDR3 RAM (1/2 GB) + on board cache like at present.
Fusion AMD with 2-4 modules of Bulldozer cores + 320 -> X (more than 300) stream processors.
TDP at or less than 50W.
The real question is in the interface and software, not the box itself. I don't expect to be amazed at all by the hardware next to the TV, its how they use it!
Do you know what its like to live on the far side of Uranus?
