Those comments weren't really directed at your questions. They are a response to grossly mistaken replies by another.

You decision to stick with the D800 makes very good sense! At some point it might be the right thing to go for a new camera, but you probably won't have any doubts about either which camera or when! It is when you need it. And you will know!

I too have the Holy Trinity plus others, the D800 and recently the D5. I use the D5 for wildlife and action whereas I use the D800 for macro work and other things.

The D5 has better low light capability, higher ISO capabilities, faster bursts, up to 14/second, etc.

Decide what your needs and desires are. Wait for the D6? Why not wait then for the D7 or better, the D8. At some time you purchase. There will always be upgrades and improvements. if you keep waiting then you will never buy another camera. Of course, that saves on the pocket book!

Erv has a D750 talk to him about it. It does a good job as well.

I agree to a point. I have both a DX (the D7100) and an FX (the D610). They have "approximately) the same pixel count. However, the D610 (FX) has better low light sensitivity because of the larger diameter of each pixel. Yes, I use the D7100 with FX lenses for Nature and birding. I use the D610 for (Nearly) everything wide angle to normal distance. The key (assuming you have both cameras) is to use the one that best fits the requirements of the shot. Its tough to shoot a wide angle using a DX because of the extra "reach" the DX provides. In essence, the DX makes a 10mm wide angle appear similar to a 15mm lens on an FX (with some differences to focal area and aperture). I consider both FX and DX cameras to be valuable tools and (as with all tools) the photographer needs to choose the one that fits the current needs. However, just like hand saws, table saws, band saws, and jig saws, the user can do quality work with any. But, using the correct one makes a quality job easier if the user knows how to use the tools and take advantage of the abilities and knows to use the proper tool at the proper time.
I generally keep a wide angle to 75mm lens choice on my FX (D610) and a telephoto or telephoto zoom on the DX (D7100). Key word is generally, as I will put the long lenses on the D610 when I shoot low light (not long exposure). And I agree that, given care and knowledge by the photographer, there is very little to no difference between images. HOWEVER, the difference is the ease of arriving at the photo. Long reach is easier with a DX and wide is easier on an FX. I use each to it's advantage and carry both nearly all of the time.

A bit old but a correction: The D100 and D200 also have DX sensors....
