Having spoken to someone with the H920+ I'd say that unless you have a pressing need for a new drone *now*, it might pay to wait. They are very happy with the upgrade.
Yuneec have shown a lot more commitment to customers with their existing models than DJI, and from what I've heard, there are going to be some good things coming out this year. They're not so good at communicating that out to customers, but I think they are going to remain competitive, despite all the noise coming out of the other company.
As for the Inspire 2, some reviews are suggesting that unless you go all in on the top model, you're actually better off getting the P4Pro.
If you've got the CGO4 and a lens you're happy with, are you going to get any extra business after you drop a few thousand on a new drone?
