I had another thought I wanted to add: Some fans have drawn comparisons between the stone-like Star Wars logo to the logo of Monty Python’s Life of Brian. (Obviously, this speculation is a bit of a stretch, but with it being so far out, I don’t think a little speculation will hurt anybody.)
If the person who designed that logo was familiar with the premise, perhaps it hints at some similarity between Waititi’s project and Life of Brian. If his film is going to explore the origins of the Jedi and their relationship with the Force, maybe it will play around a little with religious satire. Life of Brian’s subject of satire was religious dogmatism. We see in the film how people misinterpret Jesus’ message, and we see countless people argue interpretations of Brian’s “messages”. Maybe we will see how the Force brings these various beings together for some peaceful, common purpose, but those beings will immediately begin to disagree on that purpose, and we’ll see the different factions split and fight each other, leading to the creation of groups like the Jedi and the Sith.

While I don’t think it will be a straight up comedy, Waititi’s projects have an interesting mix between drama and humor, so it will probably have both funny and serious moments. Waititi has mentioned that Monty Python’s Flying Circus was an inspiration for Jojo Rabbit, so I could easily see Monty Python also inspiring his next Star Wars project.

Anyway, totally a far-fetched guess, but this is based on the very little evidence we have been given so far.
