I'm invested in Nikon with their dslrs and glass, but have been holding off adding a mirrorless body until I was sure Nikon produced one better than my D850 and D500 combination. If they didn't come up with one by spring, I was going to move to Canon, but wasn't looking forward to selling most of my gear and buying all new gear. From the specs, it looks like the Z7 II is better than my D850. Image quality will be virtually identical as it's the same sensor, but AF capability and speed should be significantly better, fps goes up and keeps 2 card slots and handles a vertical grip. I can still use most of my existing glass and then start adding Z glass. What is really selling me is the price points at $3k for the Z7 II, which is $500 less than I paid for my D850. That price "decrease" is rippling through Nikon's higher end product line to the benefit of Nikon's customers. I'll wait to (pre)order until I see some independent reviews, but I'm happy with what I'm seeing so far.
