I dunno what it means, but it was reported in the Latest MBA update rumour... All of the stand-alone MBA SuperDrives have apparently been pulled from Apple Retail stores. You can still order them online... but why they've been pulled is beyond me - unless the new MBA needs a different drive? Or it'll include a drive? I highly doubt that, but who knows. I can confirm that in the Eaton Centre store in Toronto, Canada - there are no MBA Superdrives on the shelves.
