you are so right , Nikon has over 14 stops DR because of the low read out noise and I have show how to use it compare to my Canons many times here at dpreview.

Now, 20 stops of DR can not a lens handle because of flare etc so my question will be, what shall they do with the 20stops DR? Read out the signal twice and build up a HDR picture?

It's a sensor designed for a video camera. It would allow the user to shoot in a relatively dark room, then go into a brighter room (for example) without cutting and without having to change the exposure. The video would be graded in post to achieve the contrast levels required for (and exposure transition from/to) each of the locations, allowing for a huge amount of control.

It would also be useful for shooting backgrounds for effects shots by allowing compositors to match lighting between full DR real/CGI elements prior to final grading.

There's a big difference between still photography and movie work!
