Given Apple's recent advertising around this product, I wonder if it's coming sooner than later. Intel's IDF starts on Sept. 10th and could be the day that the processors and thunderbolt controllers are officially announced. Perhaps the new Mac Pro will get launched along with the iPhone on the same day? I wouldn't have suggested this before, but the planets may be aligning.
Another thing I would bet money on, is that the iMac does not see a refresh for at least a month or two following the new Mac Pro to give fence sitters a chance to jump on the higher margin Mac Pro without the lure of a refreshed iMac to sway them the other way.
