Hexacore Xeon-based Mac Pro Soon !?

It has been quite some time that we know specifications and availability date of the new Intel hexacore Xeon. We already have indicated that it should find its way in a future revision of Mac Pro to replace the current 32 nm engraved Quad Core Xeon. The name of this hexacore CPU is now know, Core i7-980X, another cheaper (and slower) model should also be available, Core i7-970.
According to difference sources, this new CPU should become available in March. So, if Apple and Intel are still engaged in a tight partnership, Apple might have the exclusivity of such CPU (as for the Nehalem Xeon) for a couple of days or weeks. So, if you are waiting for new Mac Pro to change your current model or purchase your first Mac Pro, then get ready after the second-half of February, it should come within the next three weeks. 
If we look at Apple's history, we should also have then new Mac edition graphic cards released at the same time, the much anticipated and expected RAdeon HD 5870.
