I wouldn't worry. I'm sure there's a theoretical limit, but that will
change over time. It wasn't all that long ago that no one thought it was
possible to put _giga_bytes of information on a 2" diameter disk platter.
I'm sure the continued technology race will find a way to put more CCD
elements into a given space.
Unfortunately there's a limit to how many MPix you *need* to put in a given
area, as visible light can only carry so much information per area, even
with perfect lenses. Allowing for non-perfect lenses, I'd say we're already
close to this limit (N***n D1X with 5,5M rectangular pixels, or 10M
interpolated square pixels.). I wouldn't hope for much more than 20MPix
from a digital camera, unless sensor area is increased beyond 24x36mm
("digital medium format"). I seriously doubt this would catch on amongst
consumers who now fall in love with smaller and smaller cameras, and never
print larger than 20x30cm anyway.
