I am also interested in the Mini 5 Pro. I currently have a 
Mavic 3, 
Air 2s (for its SDK capability), and 
Mini 4 Pro. I actually fly the 
Mini 4 Pro the most, especially since I have the RC 
Pro 2 controller now. I think in my case, the Mini 5 Pro might come close to replacing the 
Mavic 3, except for its wind resistance and adjustable aperture.
As for commenters who are concerned that we won't be able to get them in the US, there are now Mavic 4's in all the different configurations available on Amazon. Hopefully the Mini 5 Pro will be, too.
