Following the screenshots detailing Nuance integration in iOS 5 through Apple internal settings, Chronic Wire reports new MacBook Airs may be coming out on Wednesday. Chronic had a good track record in the past pinpointing various Apple rumors and he seems certain the new line will launch this week, on June 15th. However, he didn’t post any tech specs of the new machines – though it looks fairly obvious that Apple will implement Sandy Bridge processors and Thunderbolt technology like in the iMac and MacBook Pro 2011 refreshes. Several reports in the past months pointed at Apple aiming at a June-July release for the popular ultra-thin laptops.

Meanwhile, 9to5mac also claims Apple will we holding retail store overnights on Tuesday for a Wednesday product launch, but they couldn’t confirm what the product could be. They don’t believe it’s the new MacBook Air family like Chronic Wire does, but it could be considering recent speculation.

We have since heard from a source that there are still some current generation MacBook Airs shipping to retail stores across the world into the next couple of weeks. Because of our own independent information, we doubt a new MacBook Air launch for Wednesday. It does make sense though based on the scheduled retail overnight.

Other products recently rumored for an update would be the Mac Pro Server, Mac mini server and Time Capsule/AirPort Extreme stations, which several bloggers believed would be unveiled by Apple at WWDC.

Update: Chronic Wire now reports Back to School promo material will be put in place during the retail overnights on Tuesday, with a launch on Wednesday alongside the new Airs. The Back to School 2011 promo was initially believed to be set for a WWDC announcement with possibility for students to get the usual iPod touch with the purchase of a new Mac, or a discount off a new iPad 2.

Update #2: MacRumors initially posted part numbers of what they claimed to be the four models supposed to become available this week. In a tweet, they later confirmed the numbers were for unlocked iPhones. Currently, Apple offers four MacBook Air models with 64 GB and 128 GB SSD options for the 11-inch, 128 GB and 256 GB for the 13-inch.
