The expected announcement date for the D700x is Dec. 20. D700x has
everything the D700 has, except the shooting rate at full resolution.
The sensor is 24+ MP - while Nikon isn't officially admitting this,
it is the one used in the Sony alpha-900. The D700 will be officially
discontinued then, as by shooting at 12 MP the D700x will match its
burst speed so the D700 is redundant. Price is a big question but
expect the USD price to be well above that of the D700.
Personally, I am surprised, I expected first a D3x aka D4. Given that
the high-dollar market is with the Hassies, EOS-1DS MkIII and the 37
MP Leica vaporcam, and the global downturn, perhaps Tokyo decided that
sector is overcrowded?
Any event, D700 was just as good as the D3 in construction, only speed
was a difference. Did I forget to say D700x has the 25.6K ISO setting?
