The great thing about the D600 is that, from what my friends have seen, it includes the U1 and U2 modes of the D7000, meaning that we all now can Adorama our old D800s and D800Es and get what we really wanted in the first place: a smaller, lighter, smarter version of the D700.
Simple observation of decades of Nikon's go-to-market strategy shows us that Nikon introduces a top model first, then the next simpler, less expensive model below it, and so on until it gets to the cheapest bottom model of any line. Then it starts again with a new flagship.
This way people bite at the top, as with the D800 and D800E that everyone like me has already bought. Just when we all get ours shipped, Nikon introduces the next model down, which is probably what we really wanted in the first place.
There is plenty of room in Nikon's 2012 line between the $1,100 DX D7000 and the $3,000 FX D800. This could be the $2,400 FX D600, so long as Nikon goes ahead with it and doesn't kill it, as they did with the D700X, before it ever sees the light of day.
Nikon having introduced some more reasonably priced FX lenses recently isn't necessarily related; the world is loaded with compatible FX lenses made since 1959, and all made since 1977.
