I'm pretty sure nothing has been announced, so it's all speculation at this point. Prior to The Force Awakens, they had clips of TFA in Star Wars: Path of the Jedi at the theater in Tomorrowland (Where they used to do Captain EO). I wouldn't be suprised if they do something similiar this fall for TLJ.
Edit: In the fall of 2015, TFA clips were just taken from the existing trailers that had been released. When I saw it again a year ago, I noticed that they had changed it to include even more from the movie. So, there's already a history of them updating the film.
