Apple have something very special planned for the 2013 Mac Pros. I can tell you that much. They are going to redefine the professional computing landscape. Why do you think it has taken this long for them to release it? I don't actually have any hard evidence but the circumstantial kind is mounting heavily. The Apple faithful will be rewarded whereas the doubters will be thrown into despair. I fully believe that companies like Intel will be rushing to implement this tech, whatever it may be. You have been warned.
