I look at camera bodies like computers, they'll never stop advancing and you always get marginal improvement on performance when you upgrade. However, I'll only upgrade if there is significant improvement from what I'm currently using because I know they get obsolete fast.
One might argue that your DX0 / DX00 / DX000 will last you another 5 to 6 years because it's a great camera. However when the industry is moving forward, your camera will become RELATIVELY outdated. Only you can decide when you want to upgrade and why. For example, I'm still surfing the web with a 3 years old $150 netbook because it serves me well while my friends all upgraded to $1500 ultrabooks for faster processors and longer battery life.
The camera itself is just a tool where only the user can justify their cost. Some people use a fancy mouse with high precision that's well over $100 while others use one that's less than $10.
Don't forget wildlife photography was never ment to be cheap, and while you're happy to pay for certain features, there are only a small percentage of buyers will find it useful. Let's ask ourselves what are the actual percentage of the potential camera buyers are serious wildlife/sport shooters? Don't get me wrong, I have also invested my share of $$ into wildlife gears but I always knew that it is expensive to get the right gears for this task. And I have always strike a balance between features and what I'm willing to spend. From there I expect that my gears will have its limits unless I'm willing to take a second mortage to fund for the top end gears.
Personally I'm intersted in the D600 and the D800 and I understand when I settle with either one of them, I am accepting the fact that I'm not getting the performance of a D4 because I am not willing to pay for a D4.
