Don't forget but that not all 6MP images are of same
quality because true color 6MP images are much better
than the the interpolated 6MP images that come out
of these DSLRs. A 6Mp dslr is not a true color 6MP
image, its only got 6MP of partially color sensitive
pixels. I think you have to divide by four to get
the true color resolution which of course is 1,5 MP
from a "6MP" DSLR.

Kodak. When the high end Kodak picture disks scanned from 35mm came out, 
the images were scanned at 6mp.  Their advertising and marketing 
department decided that a 6mp image equaled film.  Everyone else picked 
that up, and ran with it, Kodak continued to use this figure until they 
were marketing the DCS 14n which had a 13mp resolution, which they then 
claimed equaled film.  The 6mp figure slowly disappeared from various 
places on Kodak's web site, since they no longer seem to support scanned 
picture disks.  I don't think you can find it on any page there 
anymore.  The 13mp figure is disappearing as now as well.  I don't know 
where 10mp comes from.  The figure I trust postulates that 35mm film is 
capable of holding the equivalent of 32-34mp of image data.  I don't 
remember how that figure was arrived at or where I read it, but I agreed 
with the analysis at the time and have seen no reason to revise my 
opinion since.
