MacBook Air Update Coming in Mid-July?

Many customers have been waiting for Apple to begin shipping its long-rumored updated MacBook Airs, bringing a significant performance improvement to the line with the incorporation of Intel's Sandy Bridge platform. A number of reports had pegged the release for the June-July timeframe, but the June dates are essentially out of the picture now and Apple has been said to be holding the release until it can offer OS X Lion preinstalled on the new machines. 

Chatter is now beginning to coalesce around a mid-July launch, and we've been hearing that Apple may be planning a MacBook Air launch for the third week of the month.AppleNApps seems to agree, with several sources there reporting that Apple plans to release the new MacBook Airs alongside OS X Lion on Tuesday, July 19th.

Sources have indicated to AppleNApps that Apple has an internal launch date of July 19th for Mac OS X Lion and a refresh of the MacBook Airs. This is the target date under which the company is currently operating, though both sources are indicating that things can change. Our sources have just seen indications, and can’t be entirely certain, but if everything goes according to plan there will be a new MacBook Air shipping with Lion starting July 19th.

That would coincide with Apple's earnings announcement for the quarter just ending, providing the company with enticing discussion fodder for the conference call. 
9 to 5 Mac also reports that it has been hearing Thursday, July 14th in the "rumblings" regarding a launch for Lion and new MacBook Airs, adding to the increasing consensus of a release right around the middle of the month.
