All I know is that this is a helluva lotta fuss over a now slow, outdated, overpriced system based on dead technology (PPC).
PPC is far from dead.
Mind you, the Cell processor of the PS3 is PPC based, (as well as the processor of the Xbox 360, which is essentially a slimmed down Cell processor).
And AFAIK a new Cell processor has been released very recently.
