An addition:

Fresh from the 4870 list, Epson just announced two new scanner 
models:

Wet mounting holder included :-)  Higher resolution up to 4x5 
thanks to a dual lens system, the 8x10 will not have the 
higher resolution I think as it probably will be scanned on 
the scanbed itself and use the same lens + focus that is used 
for reflective originals. The 8x10 item is called guide 
instead of holder so that's what I base my assumption on. 
Quite smart as it still will be a fixed focus system but this 
time the wider lens will focus at the scanbed only and the 4x5 
and smaller filmholders use the other lens with the higher 
resolution and focus at 1 mm above the bed where the film is 
in the holders. One would expect less DOF in the lens systems 
and sharper scans than we were used to in the older models but 
the oversampling CCD matrix sensor of Epson will still need 
sharpening at some stage. I think a true optical resolution 
above 3000 PPI for 4x5 and smaller isn't impossible. 4 Dmax is 
claimed, but that has always been a bit high though 3.2-3.4 
should be possible with multi-sampling.
