The image on the Nikon Rumors website shows a non-AI 55/1.2 lens mounted on it, with an early 43~86 Zoom-Nikkor next to it. The ad recreates a Nikon F ad, I have somewhere in the closet. I'm going to guess that it has the flip-up AI lever used with the F3, FM/FE, EL2, and Nikkormat FT3. That's retro.
$2800 for the same sensor used in the D4- if the build quality is good, I'm sold. Price- about the same as the last Nikon I bought, an S3-2000.
It's much cheaper than my other cameras that I use with Nikkor lenses.
