What is somewhat interesting about this is that of all the CCD scanners on the market (excepting the Leaf, as noted) Nikon is probably best set up to do a real B&W scan. Unlike most which use a triline CCD sensor with a R, G or B color separating filter for each line, the Nikon doesn't use color separating filters on the CCD, but rather uses colored LEDs to produce the separations and a one line sensor (with all but the LS8000)
It seems to me that they could have produced something approaching white light by firing all LEDS at once with a diffuser, and read the neg using the one bare CCD sensor line. I think they would then have a bit more brightness to work from, if required.
