Note: multi-core physics still... quite frankly, SUCKS.
Example: PS3 Cell BE.
So what does that mean...?
...nothing. Just that we have something to talk about. New hardware doesn't necessarily mean we will have better games, or better performance, until we can actually code. No offense, but multi-core or multi-threaded computing still sucks so much up until now thanks to coders' inexperience (for the most part. Not all coders suck, though, but most of them kind of do now). Dual-core support is barely implemented.
My conclusion: hardware is just "improving" faster than we can actually use them. And when we do, we just find out that... it's just the same thing manufactured to be a bit better for one aspect or another. I learned my lesson with Intel Atom.
