Hi, I have a 2009 Mac Pro with two 23" aluminium displays. I'd like to (initially) replace them with a single Apple 27" display. I'd then probably add a further 27" display at some point after that. Since no extant Mac Pros support Thunderbolt I'll have to buy the Displayport version of the display. So, my question is - is it remotely feasible for Apple to ship a 2013 version of the Mac Pro without Displayport support? Best Regards, Julian.
