I think that's a very valid point Bill. My whole philosophy towards my kit is changing. I was thinking this morning and asking myself what I need in a DX camera. The answer is I only actually need it for wildlife, my D800 does everything else. How often have I seen Canon users out and about photographing wildlife and the most common kit is a 7D + 100-400mm IS lens, a very efficient two piece package it seems. Until the Nikon 80-400mm AF-S arrived Nikon wildlife shooters have been forced to use a range of different lenses for various focal lengths or go 3rd Party, or, buy the ultra slow Nikon 80-400mm D.
I am happy with my D7100 because it is light and well balanced, a lot of camera in a small package. My way forward I think is to sell my existing lenses (300mm f4, Sigma 50-500mm OS) and fund the new 80-400mm AF-S when it's price drops some more.
What I really want is just a two component package and it may be time to make life simple. I am starting to feel that my D7100 (or even eventually a D400) + 80-400mm AF-S would tick those boxes.
