I feel that they won't. Here's why: It seems to me that the current Thunderbolt display is geared heavily towards MacBook owners, rather than a pro user who would be purchasing a new Mac Pro. With their heavy marketing slant on '4K', it seems unlikely they will try to offer a new non-4K display to pair with the nMP. Coupled to this the potential high price and low uptake by 90% of Apple consumers of a new Apple 4K display, they may leave the creation of 4K monitors in the hands of other manufacturers. That said, the fact that they could sell a lot of TB2 displays to not only nMP buyers, but also to future buyers of TB2-equipped MacBooks, might signal a good chance to make the switch to TB2 on the Apple Thunderbolt Display and maybe add that new 75% reduction in reflectivity as they did on the new iMac too. Feel free to prove me wrong though - I am in the market for a new 27" display to go with my 6-core nMP!
