Sharp readying 1/2.3-inch, 20.2-megapixel CCD destined for noisy point-and-shoots

As you probably know, megapixels aren't everything. In fact, the more of them you cram into a smaller space, the noisier your images will be. So, you'll forgive us if we don't exactly shout from the mountain tops that Sharp has managed to stick a whopping 20.2 megapixels into a CCD only 1/2.3 inches in size. That does, however, give the RJ23G3BA0LT the highest pixel count in that size range. That's gotta count for something, right?
