And yet... no D700x, D800, D900 or whatever Nikon decides to name the D700 replacement.
Thom Hogan says he doesn't think there will be a D700 replacement until next year. I'm thinking he may be right.
The big question will be how Nikon structures the levels of the Nikon DSLR line-up. Most people have been thinking of the coming update as a replacement to the D700 having a much higher megapixel sensor.
It's possible the replacement may be a D700s, following in the footsteps of the D3s upgrade. This would see the D700s getting the D3s sensor.
If this was the case, then that leaves the door open for a D700x with something like the D3X sensor. Nikon probably didn't want to do this while the D3X was relatively new, but if a D700x was timed to be introduced just before the D4X comes out, then I could see them having no problem using the D3X 24 megapixel sensor.
This would give Nikon a rock solid DSLR line-up covering all bases.
A D700s at 12 megapixels for super high ISO use for those that prefer a compact pro body.
A D700x at 24 megapixels for super megapixel goodness for those that prefer a compact pro body.
A D4s at 16 megapixels for super high ISO use for those that prefer a full size pro body. I anticipate the D4s to be about a stop better at high ISO than the already incredible D3s.
A D4x at 32 megapixels for super megapixel goodness for those that prefer a full size pro body.
