And I sincerely hope we do NOT get time travel in it. So far the only show/film I have seen that figured out a way to handle it without causing the whole story to implode on itself is Doctor Who.
Time travel is old trope now. It is overdone, and it no longer falls within the purvey of possibility. This new one will have an "ending". That should be interesting. Also, I have no idea how many movies are planned in this series. I do believe that the story has been written in advance, however. It does not appear to be made up along the way. One movie seamlessly continuing the previous one....
