Re: Whither MIPS?
It was never going to happen. For reasons I still don't fully understand, people get wedded to instruction sets. And, as AMD will attest, you can struggle to achieve market share even when you're pumping out an instruction set people want. I could see Imagination's thinking---the merging of GPUs and CPUs---but the market for a MIPs processors is tiny.
As for who'll buy it: nobody you've heard of for not very much.
