I'm going to tell you a secret: my camera body doesn't really excite me any more. I used to think things like 4K video and full frame image sensors were essential, and cheerfully abandoned Canon when the Sony A7 III came along. It was the camera body that made that decision for me. I'd have to sort the lenses out after the fact.
Nowadays the A7 III isn't as exciting, but I don't feel any need to replace it – and there are two main reasons for that. Firstly, there are all the factors that made it so exciting when I bought it. It was an excellent camera, well ahead of its time in terms of specs, and it's still darned good.
