I disagree. Dynamic recompilation wouldn't help with the fact that x86 just doesn't have an equivalent of SPUs. They can be emulated, but they will be nowhere near as fast as the real thing. You can reliably emulate the PPU but that's about it. I've programmed for the PS3 and the architecture is so different to x86 that any emulation would have to somehow make up for the hardware that doesn't exist in x86. Early games for the PS3 didn't even use the SPUs, or barely used them, running mostly on the PPU, and those games should run fairly decently fairly soon. But latest games like The Last Of Us, where the SPUs have been pushed to the limit? I wouldn't count on that being emulated anytime soon.
