Several people in this thread said that Pentax should have used a larger sensor, 1.6" or 1.7" like in the Panny or Canon models. The point I was making is that these sensors are not backlit, so would not have been an improvement and actually don't perform quite as well as the smaller backlit sensor that Pentax chose. In this case just comparing sensor size isn't valid because the technology is different.
Price is a marketing thing, nothing to do with engineering. Pentax marketing dept always seems to come out high and back off. They think the camera will sell sufficient quantities at this price or slightly below. Those who disagree won't buy. If sales are below expectation, they'll drop the price. For now it is what it is, buy it or don't.
