I could see a 980 or a 970 being made into a Mac Edition card, simply because power levels are much lower, compared to the 700 series. However, like with most hardware that goes into Macs, Apple's hardware certification system is proprietary and EVGA would have to modify the power and performance levels of such a card to be able to qualify as a Mac product.
That's not to say it won't happen, but EVGA has to go through those extra steps to get them to be officially supported for Mac systems.
