Theory: The Mandalorian directors roster is a way to road test talent for potential movies. Filoni, Waititi, Howard etc. could be doing this as a stepping stone to a more direct role in Star Wars films/live action.

Waititi probably doesn't need to be "road tested" but it's possible with LucasFilm being it's own entity and Star Wars being a bit further from his style that he's been given an episode to direct as a way to test how his direction translates to Star Wars.Filoni is a master of directing animation, and an episode of live action could give him the means to directing a movie, he is George Lucas' protege after all.Same idea for the other directors. via /r/StarWars https://ift.tt/2ygep2d
