High-res digital video has been available to the multicopter community for a long time now through https://www.dji.com/fpv. First released by DJI, later the technology was licensed to others (at least the camera / VTX side of the electronics), se for example caddex vista / nebula (https://caddxfpv.com/collections/dji-1).
DJI seem to have diverted their supply chain from hobbyist FPV to this new drone. Supply for all DJI FPV gear has been very limited ever since they filed the "V2" goggles (for the Drone) with the FCC.
I'm hoping they keep their hobbyist/DIY FPV system going though, as it blows everything else out of the water. Analog video is well, bad, open source alternatives are either abandoned or mediocre, and the Divimath/Fat Shark system is not even comparable in terms of quality.
That makes sense though.. they're probably putting initial production of the V2 goggles into the FPV kits, and running out their supply of independent V1 Goggles.
My guess is at some point soon they'll be selling the V2 goggles on their own for the hobby use case.
I guess all the things you mention is why they continue to get my money. Bought the drone yesterday to compliment the Air2, which I absolutely love, and can't wait to try it out.
