Here's something else to think of: It's nice to have the most capable, versatile, technically advanced (better than) camera system on the market. Right now that's probably the Sony A9. For a hobbyist like me that camera, or any other that costs that much, cannot be justified so I'll most likely never own one. Nearing retirement I'm going to have to count my pennies in the future. Do I still manage to make good images with my less capable, cheaper Z6II? Absolutely, yes. I certainly don't get the number of keepers of fast-moving wildlife that I would get with the best, most capable camera, but I still manage to get good images. I shoot different types of images such as wildlife, landscape, architecture, macro, etc. Wildlife is only a portion of what I do, and birds in flight even less. I don't believe the top gun cameras are much better at most things not related to fast-moving wildlife.
I would challenge the Sony A9, Canon R5, future Nikon Z9 shooters to post more of those absolutely stunning images that could not have been made with a lesser body. When you show me enough of those I might be persuaded to spring for the top gun. We should be talking more about results (with posted images to illustrate) and less about features.
