Sorry, my statement was a bit misleading--I'm referring to the future
potential of digital SLRs, based on what leading-edge practitioners of high
end digital photography have achieved, and assuming this trickles down to
mass-production SLRs. Stephen Johnson got 18 stops out of a Better Light
6000 using different gain settings on each of the three 14-bit sensors in an
experiment he did last year. If you're not familiar with his work, check

Of course I don't expect the "trickle down" to include scanning back
exposures (although the motion artifacts can be a cool effect).

That's good to hear and very promising for Olympus. Will Canon's and
Foveon's home-grown CMOS sensors prevail over the Kodak CCD Olympus is
wedded to? I'm keeping my fingers crossed...
