heartyfisher, I think you're a bit overly optimistic. I looked at all the pictures from the camera for which you linked a picture. All pictures from that camera were taken in jpeg format. This means they were likely post-processed in-camera to reduce noise. My old D1X has much lower noise at ISO 125 and ISO 200 than that camera has at just ISO 100. My D1X (2001 technology) can exceed the performance of that camera's ISO 800, 1600 and 3200 performance if I apply noise reduction in PP to the images from it to make my images as soft and blurry as the ones from that camera.
Quantum dots... dreaming. It *could* someday help, but quantum physics is still bleeding edge. We do not have any products, of any kind, in production which take advantage of quantum dots, quantum entanglement, etc. It's not going to show in in sensors this year, or this decade for that matter.
Black silicon may show up sooner. However, it's fairly freshly out of the lab. It takes a minimum of 10 years to bring something from the lab into manufacturing. Look at Silicon Aerogel. Heavy research into how to mass produce it has been going on for over 10 years and has yet to bear fruit. Seriously, google for it. It's an amazing material, and I *know* you'd love to take some pictures of it (it's really strange looking). Silicon Aerogel would have a much larger impact on the world and net a much larger profit for its producers than black silicon ever will, and they still don't know when (if ever) they'll be able to mass produce it.
Sorry, but I really think you're a bit too optimistic about this. I wish you weren't; I'd love to be able to pick up a DX format camera with D700-level performance in the near future. But, that's not going to happen :(
