Thank you for sharing your thoughts. I suspect you are right in that you likely represent a large percentage of the buying public. In some ways it's difficult for those of us who need Nikon to move in a certain direction because of real needs or demands placed on us by those paying us to shoot. But a large percentage of people buying the cameras do not have any need, or sometimes any desire for the features.
At the pointy end of the market, the D4 has a Cat5 connection in it. This is a REAL need for today's photojournalists, but would serve nearly no purpose for non-pros. Fortunately Nikon still aims its flagships directly at working pros. The rest of the lineup, not so much.
I would say that most working pros with a D300 would be heavily invested in FX glass, with maybe a DX lens or two. This stands in direct conflict to hobbyists. So who does Nikon hew to in this scenario? Tough call. They split the middle in the D600. I am hoping the D400 shifts a lot more pro need than consumer market money.
