We received a heads-up from an Apple retail insider that Apple Stores are pulling all of the MacBook Air SuperDrives from shelves. These drives are exclusive to the MacBook Air and Mac mini Server, and the removal of the drives could be a sign that the long-awaited refresh of the MacBook Air is imminent. Recent rumors have it that an upcoming "MacBook" with an 11.6" display might be the replacement for the MacBook Air.
We had a false alarm when the Apple Online Store was temporarily off-line this morning, and that could have been nothing -- we didn't see any changes -- or work was being done behind the scenes to prepare for an upcoming announcement.
MacRumors AppleInsider also reports that supplies of the MacBook Air are getting very thin at Apple Stores. Be sure to stay tuned to TUAW for any fast-breaking news about a new laptop from Cupertino.
