That was before there was a cheap (well...) FX body. I guess 90% of the D200 buyers would have chosen a similarly priced FX camera if there was one back then. Just like I think that more than 90% of the upgraders would choose a D600 over a D400 if the price is similar.
So, why would Nikon listen to them instead of making more money? Edit: By the way, Canon has a similar lineup.
Sure, but what's wrong with the D7100 then? I really don't understand the distinction between "pro" and "consumer".
Makten, you are totally missing the point. FX is not the end all be all of photography. There are many people who do not want FX but do want DX for the advantages of the DX format given what they do. Sports and wildlife come to mind as has been mentioned ad nauseum. Also, when calculating costs, you cannot just consider the camera body but must include the supporting lenses as well ... again, advantage DX for the sports and wildlife come to mind as has been mentioned ad nauseum. Weight of the system comes to mind, again, including the lenses, sports and wildlife come to mind as has been mentioned ad nauseum. Finally, while the D600 is a great little camera, it lacks the performance specs in terms of frame rate and AF performance need for some applications, sports and wildlife come to mind as has been mentioned ad nauseum. Even the D800 lacks the frame rate and comes in at an extra 50% in cost just for the body.
The idea of a D400 is to provide high performance features in terms of frame rate, AF, buffer depth, build, and other features (e.g. 10 pin connector, control layout, etc.) in a DX body that can only be found in a much more expensive FX body (e.g. the D4 ) but still price it at or below the least expensive FX body (e.g. the D600). Those performance features have value and people want those features in a DX body.
Also, your GUESS of 90% of upgraders choosing FX over DX is just a GUESS and is not supported by the numbers I have seen in various polls and surveys. Thom Hogan's pro/enthusiast survey is a perfect example.
