Right but it sounded like Mando season 3 will not debut in December 2021 but rather the Book of Boba Fett will be what Kathy Kennedy called season 3 and season 3 of Mando will come at a later date.“We go into production right after that on season 3 of the Mandalorian.”
they already started production and I believe filming of Book of Boba Fett, Mandalorian starts in January
