How long before we see the southbridge integrated onto the CPU itself?

well you can get hybrid general purpose cpu/fpga development boards

there are several hurdles for FPGAs being wide general use though,

first the clockrate is generally slow, the fastest I last saw was about 1 GHz.

also to implement the same amount of functionality from a general purpose cpu onto an FPGA would take many many more gates because FPGAs being configurable need lots of gate overhead and routing.

i think FPGAs DO work well for massively parallel operations but most general purpose computing is not.

then i think programming is a bitch, because then someone has to program every operation you want. you can use a softcore package, which programs in a general purpose cpu, but then why even bother when you can just have a real cpu.
