Late last week, we noted that with pricing information on Intel's upcoming Sandy Bridge E Xeon processors surfacing, Apple's options for a potential "Early 2012" Mac Pro have begun to clear up. The Mac Pro has not been updated since mid-2010, and delays in Intel's new chips have pushed their availability out from late this year to early next year.

But despite the new processors now being in sight, AppleInsider reports that Apple is reportedly "questioning" the future of the Mac Pro line and whether it will even release updated models.

Although the Mac maker has reportedly developed a revision to the existing Mac Pro that may or may not see the light of day, people familiar with the matter said management as far back as May of 2011 were in limbo over whether to pour any additional resources into the product line.

According to these people, the consensus among sales executives for the Cupertino-based company was that the Mac Pro's days -- at least in its current form -- were inevitably numbered. In particular, internal discussions were said to focus around the fact that sales of the high-end workstations to both consumers and enterprises have dropped off so considerably that the Mac Pro is no longer a particularly profitable operation for Apple.
