Strengthening those claims that Apple is set to launch updated MacBook Airs this Wednesday, Amazon UK has completely sold out of the low-end 11-inch ultraportable with 64GB of storage.

OS X Lion didn’t drop last week as expected, but Apple promised it this month and it’s now a whole new week. So could OS X Lion drop on Wednesday, along with new MacBook Airs?

We apologize if this is getting confusing. At first there were supposed to be updated MacBook Airs coming today with OS X Lion, then it was reported that we’d see new hardware from Apple on July 26th.

Now, it appears that new MacBook Airs with backlit keyboards and more storage could be coming as soon as next week!

The next-gen Sandy Bridge MacBook Airs will be a lot less skimpy with their storage space and memory, according to supply chain checks. In fact, expect the minimum storage and RAM to double with the next MacBook Airs.

Apple’s next-generation of MacBook Airs are expected to launch alongside OS X Lion as early as this week, and in addition to the latest Sandy Bridge processors and Intel’s high-speed Thunderbolt technology, the new models could boast a backlit keyboard.

We’ve been hearing that Apple’s next desktop operating system, OS X Lion, will be released on July 14th. Alongside Lion, there have also been rumors that Apple will release a new MacBook Air and Mac Pro model at the same time.

Apple is reportedly set to release new machines with Intel’s Sandy Bridge chips. The new MacBook Airs aren’t expected to have an exterior design change, but instead focus on improved internal hardware. The updated Mac Pros are rumored to have a rack-mountable, narrower enclosure.  

We’ve seen keyboard style cases before, but rarely with this level of panache: the Aluminum Keyboard Buddy Case is made in a similar material and shape to the iPad 2, turning your Apple tablet into a reasonable simulacrum of the MacBook Air.

Could the MacBook Air offer a future for notebooks? That’s the belief of one Wall Street analyst who says notebooks could make a comeback with tablets coming out on the losing end.

In addition to a fancy new processor and Intel’s super speedy Thunderbolt technology, Apple’s upcoming MacBook Air may also boast the latest high-speed 400MBps flash memory.

With the Gold Master of Lion now released, the question becomes: when will end users be able to download the latest version of OS X 10.7 through the Mac App Store. We’ve heard July 6th, we’ve heard July 19th, but now a new source is positing a new date: July 14th.
