I find your meandering reflections on this issue both amazing and amusing. What Nikon is trying to do is set up too push a lot of FX consumer junk: D600, 24-85 3.5-4.5, much more to come. In a sense I think they've borrowed a trick from the music industry: re-package everything and sell it again for more money through a format change.
On the other hand, I see you still shooting wildlife images with a DX camera. And the best images I see around the web are still using a honking big supertelephoto with a D300 or D300s. I have seen some superb D800 zoo shots however. When the birds are small and don't have a fence behind them there's never enough reach. Surely if Nikon are so focused on FX sales they'll at least release the 800 f5.6 VR they patented some time ago.
