Would a powerful cpu provide such an advantage since most games are... well... gpu based? (stream processing, etc)
Depends on which aspect of the game, I guess. In terms of strictly visuals, obviously not. But as bkilian put it "the games will adapt to their environment".
There's no way DDR3 will be in the next Xbox(as primary memory) it's just not enough bandwidth any way you measure it for gaming in HD, possibly DDR4 with a big chunk of EDRAM I guess.
DDR4 is basically DDR3 but slightly faster.

Out of their entire pool of DDRx, there will be reserved memory for that kind of stuff. The current amount is unknown as far as I know, but the number "3" has been thrown around here.

Epic has been pretty clear if you want a technological leap the GPU must be close to 2 TFLOPS.

Tim Sweeney:
Unreal Engine 4’s next-generation renderer targets DirectX 11 GPU’s and really starts to become interesting on hardware with 1+ TFLOPS of graphics performance, where it delivers some truly unprecedented capabilities. However, UE4 also includes a mainstream renderer targeting mass-market devices with a feature set that is appropriate there.
