Perhaps I'm the only one, but I'm really waiting and praying for a new Mac Pro system and 30" Retina displays. Its been since 2010 for an update on the Mac Pro. Currently, I can't fathom why anyone would purchase them given the price. But the laptops have never felt capable enough for fulltime use for HD video editing (or 2K or 4K...)
Unless there's a "just one more thing" with these, it seems that the Mac Pro appears more and more dead.
