This is what I am hoping for. A gain in something in addition to the resolution. But the concern is what Pat brought up, that going to 50 MP did something to decrease the high ISO performance.

One other thought may just be file size and the time to process larger files. They are already looking at ~55 MB per image at low ISO. And file size increases with ISO.

We'll see. I think it with take some people getting their hands on the cameras to know for sure. But maybe we learn more with the announcement.
