I think it's going to be an awesome camera, but I'm still not sold on Northrup's notion that you can use noise reduction to expand the dynamic range. You're going to lose detail in the whole image with noise reduction. I suppose you could mask the shadows and apply noise reduction only there, but that's a serious pain in the ass.
In Photoshop it's pretty easy to use the luminance info of an image (with some suitable curves tweaks and softening) to create a mask in order to then only apply noise reduction on the darker areas. With an action set up it's something you could do with a single click. I'm not sure if there's a way to do that in Lightroom though.

My 11-24mm is blowing me away mounted on my a7R...can't wait to see the detail it can resolve on a 50MP sensor.
I am just not sure which 50MP camera to buy: the 5DS R or whatever Sony inevitably releases. It's not entirely cut and dry for me. No doubt the Sony will considerably best the DR of the 5DS R, but there other factors too. Hard choices. For now the 5DS R remains on pre-order. Tony's video provides a measure of comfort that the 5DS R might just be OK.
I guess you'd have to do some side-by-side testing, but it would be interesting to see at what maximum size of print (and viewing distance) a 5DS R shot + suitable noise reduction would be indistinguishable from a D810/a7R shot; where both were taken with good/identical glass AND the image was DR limited.
The point I'm making is that a D810 user (who pushes the limits of DR often) probably wouldn't jump ship, but would the 5DS models be "good enough" for a Canon glass owner to not need a Sony sensor.
Oh, and, yes, we get it - you have an 11-24. I'm jealous, ok?
