Granted they can keep improving glass technology, etc, but it is still a physical thing, not electronic, so there is a limit to what you can do, at least in the near and middle future. You probably cannot create a 600mm 2.8 lens that is the size of a walnut, just to give one obvious example.Of course, you can always electronically manipulate what comes out of the lens, but you are still limited by the physical aspects of the lens (as in "garbage in, garbage out"). So, no matter how much you shrink your sensors, it doesn't buy you too much if you have to attach these to a big lens.I suppose eventually they won't be using glass for lenses, or any kind of optical thing, but some other technology to capture the view, but that will be a long time coming, I should think.</blockquote>
