So now it is 2021.  Nikon is behind again (sound familiar?).  Sony has launched their market disrupting flagship A1 in April, and Canon their flagship R3 end November.  I get an invitation to a pre-launch Nikon Z9 presentation and hands-on trial in mid-November.  After the demo I immediately walked over to a camera store and place a pre-order.  Lucky me, I picked up my Z9 on first day of availability, Dec 24 and the Z800 on its first day of availability, April 21.
