DJI has no need to "grow." They just need to tread water. They already own some 75% of the international and domestic consumer drone market and some 65% of the commercial market.
DJI also never
committed to offering a Combo with the RC-Pro In the U.S.. They stated they would evaluate and decide if there was enough demand. So far, they haven't found enough demand. People are buying the RC-Pro in the
Air 2S Combo for $1750 and using it with both the
Air 2S and the
Mavic 3, or buying it a la carte for $1200.
