Thanks for your email. Our Pro customers like you are really important to us. Although we didn't have a chance to talk about a new Mac Pro at today's event, don't worry as we're working on something really great for later next year. We also updated the current model today.
We've been continuing to update Final Cut Pro X with revolutionary pro features like industry leading multi-cam support and we just updated Aperture with incredible new image adjustment features.
We also announced a MacBook Pro with a Retina Display that is a great solution for many pros.
I'll refrain from speculating about why Apple is waiting until next year for something really great. I do hope it has to do with Haswell though. Update: As you guys correctly pointed out in the comments, there's no good Thunderbolt strategy for the Xeon platform just yet. Apple's stance on USB 3 points to a corporate desire to maintain simplicity and uniformity across all product lines. Without processor graphics there's no clean way to route DisplayPort through Thunderbolt on a Xeon platform just yet. At some point processor graphics will come to the Xeon however...
Note that there haven't been any announcements made regarding the next iMac. Ivy Bridge was clearly a mobile targeted part (and Apple is a mobile dominated company), thus it's not surprising to see the first Ivy based systems from Apple were notebooks.
