I also hope they never make a season 4, though: not because I hate Kathleen Kennedy and want her to fail, but because I feel like Mando has exhausted pretty much all its storytelling capabilities by this point. Both Book of Boba and season 3 felt like they were stalling for time, in order to stretch a story that could have ended in one season into two. I sincerely hope they don’t stretch it out even further.
The same for me. It feels like a season 4 of Mandalorian would just be background for overlapping with Ahsoka and Skeleton Crew, with a probably return of the Boba Fett character. So it will be all nicely setup for the “climactic future event” in the Filoni New Republic film.
Right now, in my “head-canon”, The Mandalorian finished at the end of season 2. There was no BoBF or Mando seasons 3 & 4.
