I see the old $1,000 Sony DSCF707 with Nightshot at ISO 400 but ISO 3200
doesn't appear to have come till this spring with the DSC-H9, and
infrared is different from regular low light photography.

I would guess everything over 800 is pushed on the Sony. That would be
three stops faster and probably at least another two stops improvement
possible in the lens, exponentially less shutter lag, etc. Plenty of
differences. I'm not saying the D3 is a bargain or that I'm going to run
out & buy it immediately, just that 'Somebody's dream of ISO 20,000 is
already exceeded if somebody wants that. Personally, I would find a
clean fast ISO 6400 very useful, the 25600 is in fact barely useable.
