I love TFA, and if VIII and IX are as fun and entertaining as TFA was, then I’d honestly be okay with Lucasfilm ending the Saga there, and letting the saga sit as three little nuggets of the history of the Skywalker-Solo clans that won’t need to be touched again.
It’s never gonna happen though, and that’s okay. I wouldn’t be surprised if IX doesn’t even try to wrap up a story and the saga eventually just ignores the three-part story idea in the future.
