Digitimes is reporting that Apple has started shipping a small amount of components for a 15″ MacBook Air or ultra-thin MacBook Pro.

Upstream suppliers of Apple have recently started shipping a small volume of components for a 15-inch ultra-thin notebook model from Apple in November and the device could be either MacBook Air or just a thinner MacBook Pro. The new MacBook is expected to appear as early as the second quarter of 2012, according to sources from the upstream supply chain.

Obviously this would be a brand new product for Apple seeing as neither of those exists.

Apple is believed to be overhauling every major product in 2012, perhaps this is the SuperDrive-less MacBook Pro?
