It's hard to believe they won't update the Mac Pro with Thunderbolt (at least) before then. It would seem to be the one Mac model where it's most needed; for graphics/video professionals with high storage/bandwidth requirements.
Can you imagine the whining if Apple did that?
"That's it - a measily Thunderbolt port!"
And then there'd be the whining when Apple updates it in a few months with new CPUs. "How dare they? The just updated the Mac Pros! I thought I'd have the newest one for longer than that!"

Apple's back burner. While it's true that this delay is Intel's fault, I think it's pretty clear that Apple isn't very interested in the Mac Pro market anymore. They've essentially killed or "consumerized" all of their other professional-oriented stuff.
You have a very narrow opinion on what a professional is.
