Ok. So everyone's point is? Technology is dead? Nothing left to be accomplished? Hope not!
I believe the point is that cameras, like other examples of technology, have probably reached a point of diminishing returns as far as minimum requirements. Once cameras surpassed 30Mpixels, the lens is more the limiting factor, so why buy a 50MPixel camera? Not because you 'have to' in order to increase IQ...because the lens is becoming the limiting factor.
