Nikon is rumored to continue to support Z6 and Z7 models with new firmware updates. We are not only talking about extending support for new lenses but also improving functionality. It is nice to see that Nikon slowly changed their strategy and started to support older products (this was not the case in the DSLR era). If you look at the firmware updates history for the past few months, you will see recent updates for the D5, D6, D780, D850, and even the 10 years old D7100.
