Ethan Anderton at /Film has some details on Rian Johnson’s Episode VIII. Specifically, when it takes place in the timeline of the Star Wars Universe:
When Does Episode VIII Begin? ¶
Even though this was something that was assumed and somewhat confirmed back in February, we now know for certain that Star Wars: Episode VIII begins just after the final shot of Star Wars: The Force Awakens. That means this will be the first Star Wars movie that doesn’t feature an extended passage of time between the end of the last movie and the beginning of the next one.
If this is true, that would indeed be a first for a Star Wars movie, as Anderton notes. Still, there’s never such a cliffhanger as what was left at the end of The Force Awakens. Therefore, Episode VIII beginning immediately after the final shot in the previous movie makes a lot of sense.
