Basically, pixels are so small these days that even tiny amount of camera motion is going to blur a point of light between two pixels. I'm not sure how much that matters, but I think it does. So you can't make the sensors small and increase the detail you get. 20MP is the best you are going to do with full-frame, much less APS-C or 1" or iPhone size. Maybe image stabilization fixes all of this.
I took some photos on an airplane of a lightning storm today with a 1" sensor camera. ISO 5000, .5 second exposure hand-held, and they're pretty sharp. Not portfolio sharp, but good enough for some Internet Points probably. My iPhone did not do well, however. (I tried that first, then realized, hey I have a better camera with me.)
