Yes, as you say, it would be possible to produce a very high resolution
sensor today. And perhaps tomorrow it will be sufficiently sensitive,
etc. to justify the density. But the question wasn't about the sensor.
The question is whether the 4/3 lenses of today will be built to the
resolution requirements of that 31 (or whatever) megapixel sensor so
they don't have to be replaced again in 3-5 years. If the theoretical
resolution of a 4/3 lens is 2 microns what is the practical resolution
for today's glass and manufacturing processes?

Dan replied:
Well, if they had an appropriately enlarged version of the sensor from
the C50, that does 2560x1920 (=4.92mp) in a 7.18x5.32mm sensor -- 4/3
sensor is 18x13.5mm, so theoretically the E1 could do 6417*4872 = 31
megapixels. <snip>
