My only fear with the new Mac

My only fear with the new Mac Pro is that we'll be limited in our video card options; i.e., no more and no less than what Apple offers right out of the box.

Other than that, I'm really excited for it. The cooling system looks potentially revolutionary and I can't wait to see what they have in store for 4k cinema displays! While they didn't announce anything, I doubt they would tout the 4k output capabilities yet not evntually try to sell us the (thunderbolt) screen itself.
