Hehe, very funnt. You actually think that the fastest part in the Emotion Engine is the 128-bit registers....very funny indeed. The registers are there to make it possible to store bigger chunks of data in one register instead of in several as the case can be with the 32-bit processors. But rest assured that the fast think in the PSX2 is the logic behind. It uses two 64-bit integer unit (which makes integer calculation really fast) and a 128-bit "multimedia command unit" (and thats a nice name for SIMD, 3Dnow etc..) and that makes it faster, just as SIMD on the P3 is faster to the no SIMD processors. Then we have to take into account the damn fast bus speed which is impressive, the PC only has it on new graphicscards, not even AGPx4 comes cloes to 3.2 Gb/s. So what I wanted to say after this ranting is that the PSX2 sure is fast, but don't be so narrow minded and naive that you think the real stuff is the "128-bit system", because it almost never is.
What people don't seem to understand is that programming for a closed system (console etc) is very different then programming for the PC,MAC och a Unix/Linux dialect etc. The main thing is that for a console you can take advantage of every little hardware speciality that you can't with general PC/MAC hardware. So the fact that the hardware will be old in comparrison to the PC hardware of the time the X-box will still deliver a good punch, and while developers will get used to the hardware they will be able to use it better, just look at the PSX and the old games and then look at it's new games. It's a day and night difference.
