And OsitaLV is apparently just a combination of common sense observations and wish-list circle jerking.
DJI said over a year ago that OcuSync requires more processing power; but given the progress of technology, especially mobile-class processors, it's a given that they would deprecate LightBridge in favour of OcuSync.
Phantom 5 and Inspire 3 (or 2 v2) will no doubt use OcuSync - the major reasons behind Air and Spark not using it were size and price, vs. benefits. They're smaller drones, less likely to be used at greater ranges (by the average user).
