Check out the following Kodak page:
<http://www.kodak.com/global/en/digital/ccd/sensorsMain.jhtml>
and, once there, click on the "New 4/3-Type Standard" in the upper right
hand corner.
This leads to a 4 page PDF file that (amongst other things about the 4/3
system like sensitivity and dynamic range) discusses the probable future
resolution limits of the 4/3 sensor as technology moves on. They speak
of 8, 10 and 12 megapixel 4/3 sensors as well within expected future
developments. They also point out (if you read figure 6 very closely)
that the resolving power of a 4/3 system lens has a design point of
about 4.9 microns. Amazingly, this just happens to equate to 12
megapixels on a 4/3 sensor.
So, can we already predict the pixel count on the E-2, E-3 and E-4? We
can also probably confidently predict that the E-series will not go
beyond 12 megapixels. By that time Olympus will be needing more revenue
from a newer lens line.
ps: The 4/3 PDF file is designed as a folded page brochure. It's
easier to read after printing it out, double sided if you can.
