What to expect next from Nikon?

After the last D3500 announcement, here is an updated list of what to expect next from Nikon:

Unconfirmed/rumored Nikon cameras and lenses:

No news on a potential Nikon D750 replacement.
Nikon D6 is rumored for 2019 – the D6 trademark is already registered (there will most likely not be a D5s).
The long-rumored Nikkor 60mm macro lens is still expected (a new 200mm macro lens is also a possibility: the actual focal length could be less than 200mm but definitely above the current 105mm).
After the Nikkor 500mm f/5.6, a new 600mm f/5.6 PF and/or a new 400mm f/5.6 PF lenses are still a possibility.
A new high-end compact Nikon camera is still a possibility.
