Just because you see Tatooine in the trailer, doesn’t mean there won’t be other planets visited.

You obviously don’t know your Star Wars lore, if you didn’t think Tatooine was going to play a major part in Obi-wan Kenobi. It’s where young Luke Skywalker lives.

That’s like having a Young Leia series, and not expecting it to be on Alderaan.

Yes, the planet has been heavily used, but Andor will be different, the Mandalorian season 3 will be different. I’m sure there will be many other planets to explore both theatrically and in future Star Wars series.
