I'd pay sub $2K for a 12-14Mp Fx sensor body.

I don't really have a need for 36Mp.

As long as it has the minimum feature list of the D7000/D300 then I'm in

D4 sensor would be nice, D3s sensor would be nice .. doesn't have to achieve ISO200K, but high quality ISO52K would also be an advantage too.
Fast frame rates(6fps) is also a handy ability to have, as well as manual lens metering capability.

100% viewfinder is also a must have(for me).

Anyhow, I think this rumoured camera has to be in the works from Nikon .. when It'll get released is another question tho!

I'm currently accumulating the necessary funds for a D800 anyhow, and if this rumoured camera eventuates and is sub $2K territory ... and has the min feature requirements I want to see then I'll take one, plus an appropriate $1K lens to boot

I'm just hoping that Nikon sees the nonsense in a 24Mp DX sensor D300s replacement
