Actually that's highly unlikely. The problem is pixel size. Current
decent DSLR's have pixels of order 5um. Going smaller results in
unacceptable noise, purely from the photon limit. So to get more pixels
requires *big* detectors, like this one. There's a reason they cost
$30k: getting a piece of silicon this large without defects is very
difficult. Then there's camera size. The 35mm format is probably about
the largest consumers will accept, and it's even possible the current
1.5x crop format will stick. So it's very likely we'll stick to a
maximum of around 12-15Mpix for the foreseeable future. But it's "easy" to
stitch up a couple hundred of these ;).
