In the Disney+ special, "Disney Gallery: The Mandalorian "Making of Season 2", Favreau jokes with Dave Filoni about playing with fans expectations in Season 1 of The Mandalorian, before bringing Boba Fett back out of the Sarlacc in Season 2.

Notable quotes before he brought Boba Fett "back to life" can be found below with the date in which they happened:

Full Responsibility

Q: As excited as I am for season 3, I’m really curious how we ended up with what felt like Mandalorian season 2.5 at the end of The Book of Boba Fett. Was that always the plan, because you didn’t want to include that story to start your season 3 arc, or did it come about for other reasons, or other conversations within Lucasfilm?

A: No, no, I take full responsibility for everything people like or don’t like in this show. There’s no outside pressure on me from the studio, Lucasfilm, Disney, anyone. There’s pressure from within on whether or not something feels right. We challenge each other on whether something feels like it’s authentic to Star Wars, if it feels like it’s consistent with things that came before. A lot of what you’re seeing is us embracing the complications that come with the choices that we make in our storytelling.

Unceremonious End

May 28, 2020: During a panel discussion with the cast of "The Mandalorian" with ATX Festival, Jon Favreau brought up Boba Fett as inspiration for the series. He also says Boba Fett "came to an unceremonious end in Return of the Jedi." Does this end mean death? Or just that his storyline ended? It's a little ambiguous, but leaning towards dead. We'll have to wait and see when something reaches the canon screen/page/etc., but this puts a spin on all of the unconfirmed reports recently about Fett appearing in the show, which is post-ROTJ. We reported this in Jon Favreau: Boba Fett "Came To An Unceremonious End in Return of the Jedi".
