And yet the ZWO is still hundreds of $ cheaper. I assume the figure of $5k for the Atik refers to the OSC model which currently has no prices listed on Bintels site. The mono is $5.5k - over $1k more.
So if one was in the market for a full-frame OSC it sounds pretty good to me.

Well I guess that takes the Atik out of the equation for this conversation
. I thought the Atik was only $5k, maybe it went up after release.
I still think both of the new ZWOs are way over priced and you would be better off getting the Nikon D810 (or even a D810a) or D750 (don't know what model sensor this camera has). Not having cooling will not be a major issue given the dynamic range and noise performance on both of these cameras, it is brilliant, speaking from experience. Neither camera suffers from hot pixels and the noise on both cameras is very consistent and would be easy to remove during stacking.
Now the D850 has been released there are low shutter count D810's for sale for around the $2k mark and you can get them new for $2800 with AU warranty if you shop around on eBay. Either way you would be at least $1500 better off and have a camera that you can use normally or for astro. The D750 can be picked up new for $1800, which is a fair bit cheaper that the ZWO 24mp camera.
Just my 2 cents.
