This is also what I'm hoping for.

I think Apple said the Mac Pro is getting an upgrade in 2013, so it seems likely.

I really hope so too. At some point in the near future I need to get a beefy desktop with current generation / upgradeable hardware, and i'd really enjoy it being a Mac.

(caveat: its not for gaming or vm instances, it'd be my frontline local machine for benchmarking hpc codes, 'cause a mb air doesn't cut it for that :) )
