<<Both are fine cameras, mind you, but not what I want. Even if they gave me a D600 or a D7100 for free, I would resell them and put the money towards the camera I really want.>>
I for one being a past owner of the D300, then buying the D7000 which disappointed me (my experience as most loved it) and I was very firm as to my intentions towards my next DX and there was only one camera that I felt fitted that role, the D400.
I honestly believed that there would either never be a D400, as my feelings were that DX may be reaching the end of the road to be replaced by FX sensors, or that Nikon may have lost their appetite in launching a new semi pro DX. When the D7100 was launched I decided on a gamble and just bought it. What an excellent decision that was and although I miss a few functions, AF-ON, faster buffering and slower fps I can honestly say that I hold the D7100 in the same regard as my D800.
My experience is as a wildlife photographer (both moving and static), not sports or other action. The D7100 for the non professional or advanced amateur is a camera that should not be dismissed out of hand or ignored
