Would I like one? Sure, as a gift... If anyone is so inclined, PM me for a shipping address.
Until then, as Lawrence and Marcel have already mentioned, I've got a lot more to wring out of my current beast, and a lot of control-nut skills (read: nut in control) to develop before I'd consider dropping that much cash on a camera. I'd like to think that there will be a full frame in the future for me, similar to the D750, but if I never own another camera other than my current set-up, I think I can say I'll be satisfied and continue to shoot and improve anyway.
Now, if I were a professional that would need such a thing for my work, and the income both supported and relied on the best of the best being in my hands... SURE!
It sure does give me something to drool over though, just like the Aston Martin that I'll never buy. Man, is that thing shiny or WHAT!?
