New Pros could arrive this week
Part listings have appeared for new MacBook Airs and Mac Pros, according to leaked data. In particular there are four new Airs, divided between two 11-inch and two 13-inch models. Within each size, stock configurations are identified simply as "better" or "best;" custom configurations should also be available. Similarly there are three Mac Pro options cited as "better," "best" and "ultimate." A fourth option is a Mac Pro Server.
Apple has been rumored as working on a rack-mountable case for the Pro, which would help the computer better function as a replacement for the discontinued Xserve. Other likely enhancements include as many as 16 cores, and support for Intel's Thunderbolt port standard. All of the new Macs should come with OS X Lion pre-installed.
The timing of the listings appears to not only back up the arrival of new Airs this week, but also hint at an early debut for updated Pros. The latter systems had been expected to arrive in late July or early August, but Apple part listings tend not to disseminate until a product is very close to shipping. New Pros could therefore ship this week or shortly after; they may be timed to arrive with Lion, which is expected to go live on Thursday.
