Well said Albert. There is a compelling argument to sticking with DX.
I rarely if ever shoot above ISO 400. And the thought of selling my prized DX gear just to migrate to an FX environment is not warranted at this juncture--especially given the cost versus benefit argument.
Even our "love to hate" blog buddy Ken Rockwell was mostly luke warm about the D700.
As for the DX gear loosing value, that's not a big issue for me. I'm not into photography as a speculator, but as an artist. When the time comes, it will sell for what somebody's willing to pay.
For some, the D700 will be an epiphany--as it definitely fills a specific niche. But for many, the D700 is just another evolutionary notch on Nikon's never ending technological belt.
Now the 24MP D3X, well that's something to consider should I ever take the FX leap. But at this point, I'd rather spend the money on good glass and photo travel expenses.
