It has also been reported that The Mandalorian enlisted Jango Fett actor Temuera Morrison to play Boba Fett, which, if true, may mean the character will have some unmasked role in the upcoming season.
Because of that, there’s presumably foundation now for fans to hypothesize or even predict what The Mandalorian Season 2 will be about.
As an example, it’s known that Cobb Vanth is the inheritor of Boba Fett’s Mandalorian armor after purchasing it from Jawas following Star Wars: Return of the Jedi.
To me, it feels like a confrontation with Vanth and the once-thought-dead Fett is on the horizon.
