Why do people keep going on and on and on about FX vs DX. I know as many people who bemoan the lack of wide angle FOV with their full-frame lenses (me included with my effective 25.5-52.5mm 2.8 lens) as those who love the extra reach they get with the 1.5 crop.
Further, as far as I understand, the larger sensor will have a better signal/noise ratio, thus improving high ISO performance. But there are plenty of people who do not use ISOs above 800 or so, and therefore don't need that performance.
I have a D200 which is great, but will look at either the D700 or D3 sometime in the future over the D300 due to the FX format, because it suits me for what I shoot. I personally haven't shot longer than 85mm for a long time, and often consider an effective focal length of 127.5mm too long.
Horses for courses, and to paint out those who you deem to be "recklessly" buying obsolescence is disingenuous.
Some of these debates are very tiresome and reek of defensiveness.
