Exactly. I feel that apple will certainly update the pros as the airs are continuing to close in on them from a specification perspective. Apple needs to upgrade the pros a little to make them stand out as Apple's top notebook line.
Airs closing in on the rMBP? Since when? GPU wise the Air's don't come close, especially when you factor in the 750M. CPU wise, well the Airs use the same chip range, they use ULV chips which are much less powerful. Not too mention the display completely blows them out the water. They are two different products aimed at two different markets. I would say they are further apart than they were a few years ago.
