The last episode of The Mandalorian season 1 became available today, and Jon Favreau took no time letting us know when we would get more.

Production on Season 2 had already began before the first episode was even released, but with streaming service shows it never seems clear on when the next season will be. A year is all we will have to wait.
The alien he showed probably has at least a small part to play in season 2. We’ll see when we get closer to the release date. Maybe it will even be less than a year turnover. Fall is a pretty broad amount of time.
