A new DJI remote controller just showed up in FCC listings. It comes with 7-inch high-brightness screen, and an array of customizable physical buttons. Not sure if it is compatible with Mavic 3 or not.
That was my 1st assumption too... and hopeful. Then found the article on Agras models.More likely this is the replacement for the Cendence Controller for the upcoming Inspire 3 and Matrice series.
