I opined when the D7000 was released that Nikon appeared to be changing or boiling the hierarchy of the DX line, at least from a marketing point of view.
Nikon now has what I perceive to be a clear marketing strategy. The DX line to amateurs through serious enthusiast/semi-pro and the FX line from serious enthusiast/semi-pro through pro.
Strategy aside I don't want to be seen as saying Pros wouldn't shoot DX, I think quite the opposite.
In the end I just don't see the 'Gryphon' of the DX line being part of the strategy. No one really knows except Nikon - however the entire DX line has seen 2 refreshes with no site of the mythical beast.
I am wondering how many people think this is a mistake - seems to be a lot of D300(s) faithful waiting on the shores, scanning the horizons for this ship to come home. Is it Nikon's desire to force them into the FX line with its more expensive bodies (D800 min if you want the D300 form factor) and more expensive options for long lenses?
