Oh I totally agree Sony did some bizzare stuff with the GPU :P But for some reason they really do know what they're doing xD as mentioned earlier, the PS3 with the WEAKER GPU still has the first party titles that are considered to be the if-so-facto of console graphics pinnacle.
Another thing Sony did right with the Cell that more companies just have to take advantage of, is the fact that the Cell processor is AMAZING at shader and model processing, taking a MEGATON load off the RSX. So all in all the RSX is weaker than the 360's GPU by a marginal amount, but Sony planned from the start of the project to have the CPU and GPU work literally hand in hand. The PS3 is a technical beast if used to it's fullest and I'm POSITIVE we'll see that in up-coming titles, Killzone 2 is an obvious jump and gives almost every current PC game a run for it's money in terms of graphical capabilities, and FFXIII from what little I've seen looks like playable CGI xD FAR MORE graphically intensive than they're multi-plat UE3 game coming up if you ask me xD
