With Solo: A Star Wars Story staying far away from all things Jedi, the soonest possible movie where time travel could be incorporated is Episode IX, the conclusion of the current Star Wars trilogy.
Fortunately, there won’t be any lack of theatrical Star Wars tales in the next decade.
Both of these cinematic endeavors will be separate from the Skywalker saga, but that doesn’t mean some of the characters we’ll be following along with can’t use the Force.
However, given everything that movie needs to wrap up, I suspect that director J.J. Abrams and writer Chris Terrio won’t pile that on top of everything else (though I’d be happy to proven wrong).
