Judging from what I can read (but have not been following very carefully), if the Z-series Nikon mirrorless had arrived four years ago, I probably would have not switched to Fuji, but I have now reached a state of "good enough" and am not that interested in more purchases, including of Fuji gear.
Unless I win the lottery and have cash to burn, it is now late.
Having said that, I hope to have the opportunity to see the
Z6-7 in the flesh at a future NG get-together.
