I said yes for a couple of reasons.

Firstly, the whole noise thing. The results available at ultra high ISO (6400 and above) are simply amazing, and cannot be matched by film. Yes you can puch Delta 3200 that far, but the results are suitable only for 'art' rather than reality. This ISO flexibility is something I feel I could really take advantage of given a D3/D700 (not a fan of the big Canons).

Secondly, the lenses. I, like many others, like lenses to behave the same way regardless of whether they are in front of film or sensor.
