Sorry but this article means nothing. It simply states that Ivy Bridge is finally shipping in production worthy volumes. It is a real extrapolation to say that that means Apple is going to release a MacPro let alone a MacPro with an Ivy Bridge CPU. I believe they would be much more inclined to include this on the highest end version of a 27" iMac. All traditional MacPro's have been based on a multiprocessing Xeon core CPU where you can put more than one CPU on a motherboard. More likely the CPU that would be used is the Xeon Sandy Bridge EP core (See here
And that will occur only if Apple really wants to continue making MacPro's at all. Something I would not bet my business on.
