I only can say … that’s the normal way it goes. If a new one comes up and get shipped to get delivered you can see every day the price for older ones go down. I will keep my D2Xs – and if I really don’t use it for a long time after getting the D3 – I will give it away to someone how will have glowing eyes getting the D2Xs as a present for free.
But I agree with TK – sell it – but not at your Nikon dealer. And if you need a spare one, lighter one, … go for the D300.
And if you love your D2X ore can afford it – keep it.
Make a quick decision and never look back after it.
I will be in Sydney in Feb. 2008 again - hope to get good shots again.
