Ignore the GPU and focus specifically on sending graphics and sound data singularly through the Cell and you can make an amazing game (killzone and Uncharted for example)
The Cell (which is one of the worlds best CPU and GPU) doesnt cooperate/communicate with the PS3's Main GPU all that well.
Uncharted 2 unlocked half the power of the Cell by completely ignoring the main GPU, and Exclusives havent looked back since.
BTW bet on the PS4 having one 16-Core Cell Processor and one 8-Core Cell Processor. The 8-core being the mainstay GPU and the 16-core as the CPU. Expect 4 cores of the 16-core Cell to be used as mainstay Security, and one for the XMB2.
Leaving 11 Cores for general processes and 8 cores for Graphic rediculousness.
Scoop.
