The cameras at CES are likely the same prototypes I'm reading about in reviews where the reviewer states emphatically, "I was not allowed to keep the photos I took". A shot like that? Who knows how the camera was set, particularly with other settings like Active D-Lighting and High ISO NR. It's easy to show a screen shot and call it crap for the amusement of others. Yes, seven digit ISO is an extreme, and likely only useful under certain circumstances when other ISO's do not apply (my D750 could have taken that shot at 12800 with minimal noise - why would I want to shoot it at 1 million in a practical setting?), but under those circumstances I'm sure it's really nice to have.
