If I had bought a D810, I'd be very frustrated, and banging the table demanding full Adobe support for my images.
But it's a fact of life that if you're an early adopter of almost anything, the full support infrastructure won't be there. Nikon make it as difficult as possible for users by refusing to provide advance information to the very people that support their users and their market. But that's Nikon for you: they have no conception of what users want, and appear not to care.
I'm no great fan of Adobe, but in this case, it's Nikon's fault, not Adobe's.
