From the moment Apple announced the iPad Air, I have been anticipating the iPad Pro. From a marketing perspective, it seem unlikely that there would be an air without a pro, or at least, a standard model. The MacBook Air is so named, in part, to differentiate it from the MacBook Pro. The MacBook Air took over the spot that was formerly held by the MacBook, no suffix. My point is that the MacBook Air is not a product that lives in a vacuum.
