With Intel's next-generation Haswell processors set to launch in a matter of weeks and WWDC to kick off soon after, availability of Apple's 13-inch MacBook Air had begun to dry up at major authorized resellers.
The popular 13-inch MacBook Air with a 1.8-gigahertz processor and 256-gigabyte solid-state drive is currently out of stock at resellers Amazon, B&H, MacConnection, and MacMall. In addition, J&R is currently advertising that the thin-and-light notebook is only available for purchase in its brick-and-mortar stores.
Constrained availability of existing models is often one of the first signs of an impending product refresh, as Apple draws down inventory in anticipation of the release of new hardware. Apple's annual Worldwide Developers Conference, scheduled for June 10 through 14, would be an opportune time for the company to introduce newly updated MacBook Airs.
Ming-Chi Kuo of KGI Securities indicated last month that Apple apparently plans to introduce new MacBook Airs featuring Intel's next-generation Haswell processors at WWDC. The new ultraportable notebooks are expected to go on sale before the end of June.
Intel Haswell chips are scheduled to launch the first week of June, boasting more capable processors that will consume less power, leading to longer battery life on notebooks. The chips will also feature next-generation Intel HD 5000 integrated graphics that will offer a 50 percent in improvement over the previous 4000-class.
Kuo also said that Apple will likely introduce Haswell-powered MacBook Pro models at WWDC 2013. He expects that updated versions of the legacy, optical-drive-equipped MacBook Pro will launch alongside new MacBook Airs before the end of June, while a refresh of the premium Retina display MacBook Pro models will become available at a later date.
