Well granted I should have said Nikon’s AF-D (if the adapter has screw drive), AF-S and AF-P, or even current F-mount line up but I took that as a given for the purpose of my post.
My point was... That bunch of different lens types, means that Nikon keep shooting themselves in the foot by trying to maintain ‘compatibility’, and now they’re expected to build a brand new mount, fit for the 21st century, but it’s already screwed because everyone expects it to also work with previous generations tech, that was designed to work with a 50year old lens mount.
That need a mechanism for stopping them down.
And many Nikon cameras exposure systems too
. I bought a Canon instead, because the mount had no mechanical connections and was all set for the 21st century. and don’t understand why some of us find that ridiculous.
What, even if it turns out be something aimed at quite a different market segment than their DSLR users, in order not to take sales away from their DSLRs?
Ahh, I see what you're getting at. I think maybe they're trying to cover the best of both worlds ie creating a new mount for the future, whilst also not alienating their current customers? Over time more and more people will buy z-mount lenses as more and more z-lenses are developed, but in the meantime they have a full array of lenses that can be used. I personally think it's a good thing and don't see it as Nikon being "screwed". Obviously YMMV
Sign of the times, internet is full of haters that just like to complain and pull things apart just for the sake of it. I have my concerns about some of the design, but that's based on mock ups which may or may not be close to the final product. For people to be genuinely/adamantly criticising something that they don't even know what it will be like is bonkers
But. I keep telling myself that I have no vested interest in this and no connection at all to the company so even if this is a very good camera I'll just cheer from the sidelines and carry on using my perfectly serviceable for now and cheaper Sony A7

That's the thing isn't it I guess, how well the new adapter will work. If it's a case of the lens fits but performance is massively hindered then it's pretty pointless and I think a massive faux pas from Nikon. If the adapter works well (ie lens fully compatible with all features and has at least 95% the AF speed compared to using it on f-mount) then it will be a big success (imo). Time will tellThat’s because you have a mass of knowledge and you’re not one of the unfortunate folk who buy a new camera that’s ‘compatible’ with some old lenses their dead uncle left them, only to discover they don’t actually work properly, they just happen to ‘fit’.
My mileage is based on being sold a Pentax AF SLR that ‘worked’ with all K mount lenses (did it f***). The fact is that a cheap Canon EOS Camera and adaptor actually works as well as or better with both really old Nikon and Pentax lenses than a brand new enthusiast model from those 2 manufacturers.

Have you seen how many old lenses people are buying in the Sony a7/a9 thread?20years later and Nikon users are ‘hoping’ that their latest state of the art camera will work with all their old lenses
Well it is potentially like that, but for lenses you may already own, or indeed be able to buy quite cheap. Instead of having only possibly the 2-3 lenses at time of release.So it Canon get round to releasing a FF mirrorless camera things should go easier for them.
Of course, because Canon lenses, post the change in 1987, are electronic, if someone back engineers an adapter for this new Nikon mirrorless camera, there are a load of lenses available, as there is with the adapters for the Sony's. 
Have their 'dirt cheap' cameras had that many problems?
I understand that tbh, but I think also people are overlooking what some (maybe most) think. Yes in an ideal world you’d use native everything, BUT as I found out when I considered the switch to Sony the cost to change is HUGE. If you can cater for the majority that don’t have wads of cash and will take years to be able to change all lenses then surely this is a good thing?
Canon ‘suffered’ in some circles for a couple of years, but they now have 30 years of EF lenses, that will probably still be being used in 30 years time. Meanwhile on current behaviour Nikon will end up with a ‘compatibility’ table that runs across 2 spreadsheets.
It can be ‘as good as it is currently’, my point is that’s not ‘good enough’. Why use 30 year old screw drive lenses when modern lenses just work better?however what I can’t get my noodle round is why. What I mean by this is that on current bodies it is electrical components that are used to control the mechanical lever (and screw drive if you have one). What I don’t understand is why using an adapter why you can’t have the same system, ie electrical components that control the mechanical parts? Hopefully that makes sense? On this simple level there should be no difference, the adapter could just be thought of as the f-mount which (on current DSLRs) receives electrical input to control it? Obviously there’s a reason why, but on this simplistic rationale I can’t figure out for the life of me why
What makes you think Nikon owners don't get it? As far as I know they have said that old lenses will work, they haven't said how well they will work, and there will be caveats, as there is now with what cameras are compatible with newer AF-P lenses. When all the info is actually out there, rather than speculation, then those that 'don't get it' will be able to make an informed decision on whether using old lenses is for them, and how compromised older lenses will be.
As long as you are aware of any performance issues, and as you say Nikon may have pages of how things will work, and how well, what's the problem.
It may not be for you, but if people want to do it, so what. How will the new cameras performance be hit by being able to have an adapter to use old lenses available?

But those not heavily invested or fanboys would be comparing starting from scratch with Nikon vs Sony vs Canon, and their choice would be based on brand features, recognition and marketing. Not on the complexity of adaptors.
Which was the point I was trying to make.D600 / D750 / D800 and D810 also seems to have a service advisory
I have not noticed problems with the D3*** or D5*** series. Which was the point I was trying to make.
But some people don't have a choice but to work with what they have got or can buy cheaply. Would there be issues? Probably, but if it is a choice to live with compromise to use something, not use it, or change a whole system, a lot of people will make do, and that who Nikon would be catering to with this adapter. Would you? No, but then it sounds like the Canon mount does everything you want, in the past, now, and in the future.
Ah, excuse my mistake, the Nikon range isn't only FF.
