I received some information that the Nikon D810 camera will no longer be in production in 2017.
Given previous release patterns, Nikon tend to announce cheaper cameras first (D610/D750) and then follow up with a higher-end, more expensive model (D810).
The Nikon D810 body is currently $200 off. I expect another price drop in February/March.
There still no changes to the what to expect list I did back in December.
