Well now they are talking about it and suggesting a spec.
Nikon Z9 is expected in the fall of 2021
No official plans for a Nikon Z8 camera yet
Prototype Z9 cameras may be tested at the Tokyo Olympics next year
New Nikkor Z 400mm f/2.8 mirrorless lens is also rumored for the Olympics
The Z9 is described as a D6 body combined with EOS R5 imaging, α9II AF, and blackout-free EVF
46MP (previous rumors suggested a 60MP sensor)
20 fps
8k30p, 4k120/60/30p
New EXPEED processor designed for 8k
Improved AF (Object detection AF)
Two XQD/CFX type B memory card slots
ISO 64 – 25,600, Hi1, Hi2
High resolution, blackout-free EVF
New user interface (no second LCD screen on the back like he D6)
New battery: Nikon EN-EL18x
Gbit LAN, USB-C, WiFi, GPS
Price: $6,000 – $7,000
Interesting they say 45MP which says two things to me ..
Buy a Z7ii at 45 MP because waiting for 60MP ain't going to happen.
Z8 will be the 60 MP but we will wait to sell all the Z7 ii we can first
Comments
However, perhaps Nikon is committing to their new sports cameras having 46mp. This would be a departure from the past, but I would not that 46mp is just large enough for 16:9 8K video. Nikon might be saying, "OK, the pros want great low ISO performance, but the low ISO performance difference between the D850 and D5/6 is actually pretty minimal once you down sample and pros "on balance" will be OK giving that small benefit up if they get 8k video."
In that case, I cannot image the high megapixel camera being only 60mp. I would expect something bigger.
As an aside, if pros are also worried about the size of the raw files, a sRaw file could be made to be about 12mp if they combine 4 pixels into one. That is D3 performance and likely large enough for lots of pros.
Guess it's not too bad really considering the price of the D# line. I just hope a lot of the tech winds up in the Z6/Z7 models because I have no interest in a big pro style camera with a built in grip.
Consider the Z6 and Z7. Nikon probably preferred the no 2nd card no grip strategy but needed to test it. If successful, they would make that a feature of the Z8 and Z9 and allow them to differentiate their product more. As an initial product at launch, Nikon may have decided to test how customers would respond to no grip no 2nd card. They could always update the cameras if the response was negative, which it was and they did.
Now consider the Z9. Nikon may be testing, "Will pros be willing to give up a bit of high ISO performance to get 8k 30p at 16:9 plus higher resolution in return?" If yes, then the Z8 can be a high megapixel beast. If no, then the Z8 will have 20-24mp and be the sports camera and the Z9 II will be the high megapixel beast.
There is an excellent Photography Life review that delves into the sRaw files on the D850 and how Nikon got it right compared to the D810. The sRaw files are just as clean as the Raw files. Interestingly, they chew up bandwidth somehow in the processing because the buffer capacity declines which pros will not like. I believe that it is likely that even if that bandwidth issue exists, it won't matter because with all the extra bandwidth being supplied by the newer sensors and the new Expeed, FPS and buffer capacity (especially with the dual CFX cards) will not be a factor.
Pros can then shoot sRaw with no appreciable impact on IQ, FPS or buffer capacity which will be 11.3 (or so) mp. Just like a D3 and any pro complaining about resolution can still shoot in mRaw which will be higher resolution, but still a smaller file size.
Finally, regarding high ISO performance, once you down sample a D850 file to a D5/6's file size, there is very little practical difference in high ISO performance - though there is some. I personally think that the differences in ISO performance between sensors of different MP is not the issue it once was and has turned into a bit of a myth. Sure there is a difference, but I challenge one to demonstrate a practical difference in a web sized file just like I would challenge someone to demonstrate a practical difference between a 24mp and 46mp sensor in a web sized file.
Note that the difference in ISO performance is obvious when you pixel peap, but unless the end user pixel peaps (like me!!!!), I stipulate that the difference is minimal after down sampling.
Though in the past there has been a lot of marketing about how such and such camera has bigger pixels, but a bigger pixels is collecting the same light data as the 4 smaller pixels that could replace it.
And this is coming from someone that hates noise unless it is part of the creative decision. I liberally use tripods to avoid it, even carrying them with me all day when I am on vacation.

Though this does kinda seem like the Z50 is the D500 then or maybe we are getting a Z90 with the Z9.
Consider that the Z50 body only is about $850 in the US and the Z4 is about $1,400. Then if Nikon slaps a ff fsi sensor in a Z50 (the Z50 has a BSI sensor) calling it a Z3 and perhaps sells it for $1,200, how will you sell at $1,000 plus APS-C camera to anything but a niche.
Fuji is going to have a problem here. But at 5% of camera sales, they are already a niche. But Nikon and Canon have put a ceiling on what Fuji can do.
APS-C is probably 2/3 of interchangeable lens cameras. I wonder if Nikon and Canon with their RP have just cut that share in half, especially if Nikon launches my mythical Z3 and Canon responds in kind.
And where is Sony on full frame? They have nothing to answer the Z5 or Canon R and RP. Their latest release is a video camera that is expensive and limited if you are a photographer. Sony better get its act together or they will be heading back to Fuji market shares.
