At least 100 MP. The existing digicams (e.g. LX3) prove that 2 micron pixels have performance that is superior in dynamic range to the existing 5+ micron DSLR pixels.

Sensor designers have not focused only on increasing resolution. They have been optimizing all sorts of things from the beginning (read noise, QE, FWC, etc.).

You don't even need 15 MP to print 11x16. Plenty of people print less than 1 MP on 11x16. In fact, some people attend theaters where 0.7 MP is projected to a 50 foot screen, and they sit in the front row and enjoy the image just fine.

So clearly, resolution is not necessary to make a large print. The more interesting question is: At what point does more resolution fail to make any difference at all?

The answer to that is *much* different than most people think. It is very common to greatly understate the impact of resolution. 15 MP is not the ideal resolution for 11x16". 30 MP would provide higher contrast and resolution.

I started a new thread to discuss the topic:
