The average consumer doesn't need 11mpix but there is still a market for it -- professionals, amateurs, etc. Why else are they selling 16mpix+ digital backs for medium format cameras for over $10k?
A lot of clients want large prints and while you can blow up a 3-6mpix image, you won't get as much detail as one from an 11mpix image.
FYI, the Canon EOS-D30 and D60 DSLRs use CMOS sensors and both compete very well against other DSLRs of the same market.
