The D4 16mp sensor was the right choice for a number of reasons. First, for low light, high ISO shooting, it is probably the best sensor on the planet; second, it provides more resolution than is necessary for the overwhelming majority of users. (Have you ever seen the files that the D4 produces?) Unless you are making *very large* prints, the resolution of the D800 (or Sony A7r) is simply unnecessary; third, it doesn't burden the user with unnecessarily large files. I think that many people who bought D800s were shocked at how files from their 36mp cameras slowed down post processing (not to mention how quickly memory cards filled up). Finally, a 36 mega-pixel sensor requires (as mentioned above) both the best glass and very controlled technique if you are going to take advantage of its resolving power.
The potential purchaser of the Df is an experienced photographer who knows just how foolish the race for higher mega-pixels is. He also understands the ergonomic advantages of controlling basic camera functions with dials rather than menus.
This camera is not for everyone, to be sure. However, Nikon has produced something that, for many photographers, was long overdue. I think that--even at the current price point--the camera is going to be a success.
