If someone goes looking for Mandalorians and Jedi, I’m not surprised when they meet a few we’ve heard of, seeing how there are so few of each left. Meeting them never detracts from the focus of the main story. It’s more just a brief intersection.

But I have no doubt we’ll see even more characters appearing soon. A few castings have already been announced. The way their story left off was meant to be continued, and I have no problem with them doing it in live action instead of animation. And I have no problem if it intersects other stories. The major players in the galaxy are bound to bump into each other from time to time, because their interest often lead them to.
