I am waiting before I purchase a solution. I am hoping that there will be more choices with better specs as we approach the deadline. I will need a solution for over half of my fleet. DJI should be ashamed of themselves for not supporting aircraft that still have a viable, large population out there still running.
My next enterprise purchase will reflect this and will most likely not be a DJI product for this and other reasons.
They should realize that they make great products, that last! And since they last, they need to support them instead of forcing you to buy a new drone every 3 year cycle.
My Phantom 4 Pro V2, Mavic 2 Enterprise (Zoom) and Parrot Anafi Thermal will need a Remote ID solution very soon. Also my home built bird, but this is actually the easiest since I can easily tap into power.
