It’s when the current supplies run low that the interesting stuff tends to be around the corner.

Per 9to5Mac, sources have stated that supplies of the MacBook Air are dwindling ahead of an expected refresh for the product line.

Back in April, it was reported that new MacBook Air models were likely to be on the horizon, perhaps launching in June.

However, the most significant additions to the new MacBook Airs are likely to be Sandy Bridge processors and Thunderbolt ports.

Many of the MacBook Air’s rivals in the thin-and-light category such as MSI, Dell, Lenovo and Samsung are either already using Sandy Bridge processors or are about to introduce them.

Stay tuned for additional details as they become available.
