Why the D700? You would be better off buying some top class glass. Mind you as soon as I saw the announcement of the D700 I thought of you and wondered if a) you would regret buying the D3 when you could now get the same performance IQ wise in a smaller lighter body much cheaper and b) if you could resist one. Looks like I won the bet with myself on b).
I also wonder if you have both D3 and D700 if the D3 will mostly remain at home as it is so much heavier, in which case I will be first to put my name down for your D3 so it is not wasted!
There, and I am a Canon man too!
