Here is the explanation I received about the delay of the rumored Nikon Zf/Z7II/Z8/Z9 firmware updates:
“These updates were supposed to be released months ago, but they’ve been delayed because of some major issues with Nikon’s Imaging Cloud and the Z7II. Apparently, backporting the functionality to the Z7II was way more complicated than anyone expected, which is what’s been holding everything up. The firmware updates for the Nikon Zf, Z8, and Z9 are going to seriously boost image processing. About the Z7II, it was supposed to get an update too, but they ran into some technical issues specific to that model. Internal tests showed compatibility problems that need more time to fix. It’s a bummer for Z7II users, but Nikon wants to make sure the firmware is rock solid before releasing it.”
