The price is "smart"; they got paid by the military to create the military version; it probably is relatively easy to downgrade that military version to the USA version so I assume the development costs are not that high.
A lot of US governmental companies are not allowed to buy Chinese drones anymore; so the Anafi USA will be one of the few options, if not the default. A price of $7.000 is not that high for those companies
I can see it being useful for power line and solar farm inspections as they showed. I actually used my regular Anafi to inspect the metal roof of a cabin as the metal roof is quite steep and would require special equipment to do it if I didn't use the drone.
The good thing for us is they continue improving FF6 that will be used with the ANAFI USA and will be the same for ‘our’ ANAFI.
The last Good old Anafis are still on the production lines, but they stop production, still keeping spare parts for the coming years.
Improvements of FF6 are coming (such as the possibility to change the home point for the RTH or improvements on the Automated/ map planning Software in FF6).
