Nikon rumors is doing a pretty good job on passing on info.
Their latest post, suggests that the chip for the D850 may be fabbed from the same material as the D500. If so that would lead to progressive improvements with higher ISO. The D500 is not as clean as the D810 or D750 at base, at least from what I have seen on the various review sites, especially the imaging resource and dpreview comparison tool. But once the D500 is past ISO 800 it begins to surpass both of the others, not by much but it does have a marginal improvement. At 3200 and above the D500 seems to be the leader.
As nothing has been published on the sensor yet for the D850, it will be interesting to see what it really is.
Latest FPS is 8 or more, which is also impressive for full frame under 3K. And no EVF or Hybrid design, straight DSLR.
The D750 still for me is the best all round high ISO Nikon I have shot, and I use it a lot for astro work in the ISO 3200 to 5000 range with very good results.
