For those of us who almost no longer care anymore whether Apple release an updated Mac Pro or not and are seriously considering the alternatives: http://www.anandtech.com/show/5846/hp-z420-workstation-review-competition-heats-up Performance is impressive, albeit at a very high price. I have to say that I hate the HP design, it looks cheap. On the other hand the new Dell cases look pretty good, not quite up to Apple's standards, but a big improvement on the old ones. http://content.dell.com/us/en/corp/d/corp-comm/image-gallery-precision.aspx It will be very interesting to see more details of Mountain Lion. If it doesn't look like it will deliver enough in terms of GPU support then switching to Dell will look the more attractive option irrespective of whether Apple announces a new Mac Pro or not.
