Going OT slightly, am I going mad or have I seen somewhere that Sony plan to use the same Cell design, but running at 6GHz, in the next iteration of PlayStation?
This would be good news as it would mean the devs are familiar with the architecture and hence they can tap into the power of a PS4 much quicker.
Not seen that myself, everything seems to be quiet on the PS4 front, and it'll probably stay that way for many years, except for very wild speculation!
But keeping the same processor archetecture makes sense.
We've had the Emotion Engine -> Cell for PS2->PS3
And x86->tripple core PPC for the XBOX->360
Completely new archeture for those two systems.
But Nintendo did the wise thing, with the Wii's Broadway processor being an updated faster PowerPC core derived from the Gamecube's Gekko. It also appears that the Wii's Hollywood graphics is also an updated faster version of the GC's Flipper. Dev's will have 4-5 years of experience under their belt that can be carried forward. It's one of the only real times that CPU has been kept the same!
Quick edit: In the past:
Nintendo:
6502 (Nes) -> 68000 (SNES) -> NEC VR4300 (N64) -> Gekko PPC (GC) -> Broadway PPC (Wii)
Sega:
Z80 (SMS) -> 68000 (Megadrive) -> Dual SH2 (32x / Nepture(unreleased) / Saturn) -> SH4 (Dreamcast)
(Zilog Z80 - fantastic 8 bit processor, I still develop Z80 code!

)
Sony:
Custom R3000 (PS1) -> Emotion Engine (PS2) -> Cell (PS3)
Microsoft:
733MHz Mobile Celeron(128k cache) (XBOX) -> Tri-cored PPC (360)
