"D800 with a AF Zoom-Nikkor 80-200mm f/2.8D ED Lens"
Considering the D800 when they come out. I incorrectly assumed that my AF Zoom-Nikkor 80-200mm f/2.8D ED Lens was a DX only lens. If you look at the specifications, it says....
Format Compatibility Nikon FX/35mm Film Nikon DX
So, it will work on both FX & DX formats.
I'm assuming though that the reach of the lens when mounted on the FX body will be less than on the DX. Meaning that compatibility means that it will mount and function, but the focal length will be different.

Yes, it will mount and function completely on an FX camera. Its focal length will remain the same too. You'll just get a wider angle of view at any given focal length than you would with the lens on a DX camera.

Indeed what Brian said is true. Your DX body simply cropped the image; it did not change the focal length of the lens. The D800 has the ability to crop as well, either automatically in camera or of course you can do it in post-processing, so you will not lose any functionality.
However, if you want to use all 36MP on the same type of subject you were accustomed to shooting with your DX camera, you will need a 300mm lens to get the same field of view, and you will find depth of field is about a stop less.

Nikonians is indeed a great resource. I used that same lens on my D700 until a couple of weeks ago when I was fortunate enough to find a like new 70-200mm lens for a very fair price. As further evidence of the "FX'ness" of your 80-200mm f2.8, mine dated bak to my F5 days with 35mm film (... that stuff in rolls that you had to have processed - LOL) So you will enjoy your 80-200mm on your D700 very much. As Brian said, the matter of "more reach" on a DX body is simply that of cropping an FX image to DX proportions. Now you may feel you have lost reach, but what you have gained is Field of View. Enjoy BOTH your new D700 and "old" 80-200!
