But you forgot that there is certain point, when bigger pixels won't bring
lower noise levels. EOS-1Ds has similar noise level to coming from the same
era EOS-D60 or 10D despite having much bigger pixel pitch. Kodak's FF DSLRs
are even worse than that. This is caused AFAIR mainly due to much longer
signal paths.

The real test of those tiny pixels is the noise level. Canon has made
amazing strides with lowering the noise levels of CMOS sensors.
Presumably Nikon has as well because the pixel pitch of the D2X is
about 20% smaller than the 8 megapixel Canon 1D-II (currently the
finest pixel pitch of any sensor on the market).

I'll bet that even if the predictions of the EOS 2D having 22
megapixels are wrong (I'm skeptical myself) Canon will apply the low
noise technology from the 1D-II sensor to a new full-frame sensor and
create an ultra-low-noise 11-12 megapixel camera that Nikon will be
hard pressed to match with pixels that are almost half as big.

Of course, that's why it is worth of waiting for real world tests :-)

I've got you :-)

We can only guess for now :-)

  If those long lenses can cope with the 88 lpm resolution of the 12

  Mea culpa, I read the headlines backwards. In fact they announced

  It's hard to believe Nikon would bring a F6 without some plans to
  match it digitally in the long run. Cause D2x falls quite short of a D6...
