As stated in their most recent financial documents (FY2023 H1), Nikon is focusing on increasing their profit, not their market share. Therefore, I am expecting more high-end cameras and lenses from them - although they are also planning to target the younger photographer/vlogger crowds, which can lead to a few outliers - cheaper cameras like the Z30 released in 2022. As the president of Nikon said in a recent interview (see Thom Hogan's comments: https://bythom.com/newsviews/self-fulfilling-prophecy.html
), they are also focusing on B2B production of parts and components. This means, IMO, that fewer and more expensive consumer photographic equipment will be released by Nikon in the future.
For 2023 I think that they will update the Z6 and Z7 lines with more significant changes (new sensors and capabilities, improved/larger bodies, increased prices).
At least a new DX body will also be announced, but I am not sure if it will be a D500 equivalent or just an improved Z50.
I am not sure about anything else, including a Z8.
For lenses, they added a few new ones to the November 2022 roadmap - releasing them as well as the remaining ones from the previous roadmaps should keep them busy for the entire 2023. There will most likely be some "surprises" like they were in the past 2 years.
Based on the interview mentioned above, I also believe that they will be more active in the "software" area, both with new/improved in-camera capabilities, as well as with shooting/post-processing solutions (such as remote camera operation). They will add more video capabilities to at least some of the new cameras.
In terms of personal expectations, as I mentioned before, my camera bags are full, and I will not buy new equipment unless it replaces something I have. In fact, I might even start to let go of some of my less used equipment in 2023...
In terms of lenses on the roadmap, there is nothing that I need / want right now. I am still curious about that 26mm (non-S) lens that could be a true pancake...
In terms of cameras, if the Z6 III has a 30-36MP sensor and improved ergonomics, I might buy it to replace both my Z6 and D810, in which case I will let go of all my F-mount lenses except for the Voigtlander ones that I use with the Df. The Df will stay
