The Star Wars Universe

 Just wondering if any of my friends are experienced in the Star Wars universe. Specifically, how the new spin off shows are, or will, jive with the movies (7, 8, 9). (As well as the semi persistent internet rumor that 7, 8, 9 will be retconned in some way at some point.

I saw one video on YouTube where someone surmised that 7, 8, 9 were an alternate timeline because Ahsoka was one of the voices Rey hears in Rise of Skywalker, which would mean Ahsoka's dead. If that's part of where we're headed, then the end of that series might need to have Ahsoka die.

But, at this point, I don't have the entire of grasp of who is where, and when they are supposed to be alive, or not, and I'm wondering if there's a friend of mine out there who just knows more than I do.
