If you go on what a pro body sells for compared to a Z9 at $5500 USD, a Nikon D6 pro DSLR sells for $6500 USD, and a Sony A1 pro ML sells for $6500 USD, That's a $1000 difference and it's always been my opinion that Nikon had to price a Z9 cheaper to 1. stem some of the flow to Sony and 2. partially compensate for the lack of any other ML body that actually AF'ed on anything that moved.
So now they have a dilemma. Price it too close to a Z9 and you lose the value proposition. Price it too far below the Z9 and there goes some of the cream. And added to that, you better really want an ML D850 to forgo buying an actual D850 at $2800 USD
Maybe the specs will be different enough from the other bodies that surround it, because really a Z8 as an ML D850 was what the Z7 was alluded to be, so IMO Nikon is only now ?? (assuming) producing what they said they were going to make back then, and a Z7ii can be had for $3000 USD
