As for your GPU comments: I stick by what I said. The CPU is not so separated from the graphics as you say. It certainly wasn't in the PS2, and logic dictates that it won't in the PS3 either, and using fabricated knowledge of the RSX to back up your point doesn't exactly work either. Will it help with actual vertex or pixel shading? I doubt it, I never claimed anything like that. You did mention animation, however, which is a massive factor in graphics, and the Cell will certainly help in that department.
Also, have you seen this demo:

"rendered entirely with Cell", according to Phil Harrison. Now that doesn't look like something a graphically useless CPU could produce, do you agree?
Most of your CPU and GPU philosophies seem to be stuck on current PC ideas. Consoles are certainly not PCs, especially the Playstation consoles. The CPU was the main driving force behind the graphics in the PS2, and it worked out well for them. Why not the PS3? They're certainly touting the Cell as a very graphically capable CPU, afterall, wasn't one of their original ideas to use a Cell as a GPU?
