I've seen this before. kinda interesting. although obviously made up. its based on the real patent from Sony on Cell. the "GS2" should be GS3.
but not to confuse, those are the Pixel Engines, the rasterizing portion of
Visualizer, PS3's GPU. actually the whole GPU should be called GS3.
GS2 was never revealed, but it was to be alongside EE2, in a workstation.
the Phase II part of Sony's longterm plans.
