Considering they already had a box running at the keynote I doubt there is any new processor in the works. I notice also that members of the Mac dev community can pick up a new intel box for a grand, presumably fairly soon.

What, o what, will the poor fanboys and sycophants do now? The PowerPC is way faster than Intel! Just look at the <insert random oddly-weighted benchmark here>! Gaussian blur is 4% faster!"
