A more interesting question is where is the market going and which companies are trying to chase it.
I have long held the view that the market is saturated and the Z-8/9 and A1 are good enough for all but the most picky professionals.
For casual vacation photographers the new cell phones are also good enough and I see them basically ending the P&S market.
So, who is the target for a low-cost MILC, interchangeable camera like the Z6iii and its competitors? I think the target is Birders and the R6iii and competitors are ill suited and possess a photographer's view rather than a birder's view of what is attractive to a Birder.
After signing on to a birders expedition one time I have some thoughts on what would be attractive to birders.
1-Lots of reach. A birder sees a bird flying in the distance and the leader rules out certain birds and announces it as a such and such. Some birders check their sheets and are satisfied but most birders require that THEY, not the leader identifies the bird.
2-Interface with bird identification software. The birders need a picture for iBird Photo Sluth to identify a bird and binoculars don't take them, so some use their iPhones and hope for enough photo to get an ID.
3-Light weight. Birders hang binoculars around their neck and MAT tolerate a camera/lens on a Black Rapids strap but I am thinking that over 4# would discourage most birders. (I draw this conclusion because I don't see many spotting scopes out there.)
4-Low cost. Birders are not big spenders. Mostly they are cheap geriatrics.
5-Not complicated. Subect ID makes everything easier but otherwise a good AUTO mode.
In my view the Canon R-7/100-400 come closest to meeting birders needs. I feel that my OM-1/100-400 is too expensive for most birders.
So where is Nikon going? No place that makes any sense in my view.

A couple of things:
The Z6iii is not necessarily "low cost".
Other markets: landscape, reportage, travel, journalism, all are good markets for the Z6 series. As are events of all kinds or just hobbiests needing / wanting a decent camera. Not everybody needs nor wants 45 MP, or a 4k camera body. Nor can everybody afford it. Or everyone who produces both, stills and videos. The Z6 series is also a decent back-up body for people using something higher tier, e.g. a Z8/9. Because not everyone falls into the rich wildlife photographer bubble on bcg carrying two Z9/8s and glass for 20k bucks. And for those, a Z6iii is actually a great offering. Throw in some decent lenses and it covers everything one can dream of. And for the orice difference between a Z6iii amd Z9 one can get some good glass.
There are a lot of photohraphers out there, that are not sitting with 20k worth of gear taking pictures of birds and such. Or sport events.
Birders are a very small nieche market, and frankly, if you are one and need a "leader" to announce what bird you are seeing, get a grip or a new hobby... And if, as a birder, you need software to tell you what you saw, well, why not just sit there and appreciate the beauty of those animals? Why does it have to be the rarest and most special? I don't get it...
Edit: Another point regarding "Pro Cameras", what exactly is a Pro Camera? One that is used by someone earning his living through photography? If so, that would include *a lot* of bodies, including stuff like a D7000 series or equivalents. Or is it a camera sporting "pro features", if so, what are those "pro features"? And is a Z6iii, or even Z6ii, less pro feature wise than a, say, D3?
Seriously, why do consumers think they now more about target markets and strategy than the manufacturers? Limiting the camera market to the Z9 wildlife crowd is as ridiculous as limting it to the Leica street photography crowd...
