winter: No, because the circuit design and lithography processes are mature now, they weren't then. Unless something changes, the theoretical max is 22nm, which is half of what we're at today, so we'll get one good doubling of our CPUs(pretty much just more cores), and x86 won't see any significant improvements, the instruction sets are maxed out, there's no more revolution left, and clockspeeds won't exceed 4ghz.
The only possible revolution I see is if AMD's Fusion successfully integrates stream processing into the CPU with shared cache, where GPGPU offloading could then be done automagically for all applications by the CPU without having to copy data from main memory to GPU memory. Even then, there's no guarantee that it will consistently work well, only time will tell.
