Just to clear up what some people don't seem to fully understand:
For the US-
Launch 60/20GB; Full B/C Emotion Engine (PS2 CPU) and Graphics Synthesizer (PS2 GPU)
80GB (4 USB ports) Launched in Aug07 in Motorstorm Bundle and later relaunched as an MGS4 bundle; Graphics Synthesizer (PS2 GPU), No Emotion Engine (Emulated by the Cell)
40GB Launched in Oct07 and every model after except the minor return of the above mentioned 80 for MGS4; No EE or GS chips
For EU-
Launch 60; Same as first 80GB
Later models; Same as 40GB mentioned above
It's worth noting that throughout firmware updates, PS3's that were emulating the cell had gradually improving B/C support.
As for why SONY can't simply emulate both chips? See HappySqurriel's post. Last I checked the best PS2 emulater out there required 2GB of ram and prior the best required 4GB. We're talking about emulating a system that only had 32MB of ram TOTAL.
