The Mandalorian Season 3: Everything We Know So Far
7. The Core Cast Will Return
This past season introduced a ton of new characters into Din's orbit, as well as had him run across established Star Wars characters both from the movies and from previous Filoni projects. While several of them probably won't be seen for a while at least, such as Boba Fett or Mayfeld, it has been confirmed that the core cast of characters - barring the obvious exception - will be returning for season 3.
How much of an appearance, say, Cara Dune will have is unclear, seeing as how she'll have her own show by the time the next season rolls around, so she'll likely be embroiled in her own business while checking in every now and then because she - like everyone Din comes across - is determined to be friends with this awkward loner whether he likes it or not.
Not sure yet what role Greef Karga will play in season 3, but it's always nice to see Carl Weathers show up regardless of context.
