Here is the gizmodo post I saw on it last night: http://gizmodo.com/5917901/tim-cook-...ming-next-year

Tim Cook wrote to a customer:

Franz,

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.

On second look, there is no mention about the 17" but that is what everybody is upset about, so I wouldn't be surprised if they do something to replace it at some point.
