I'm assuming that Kishi will finish the current Arc before the release of the next movie. The movie launches in Japan on 6 December.
It wouldn't make sense to have a movie that is supposed to take part after the main story release before that part of the story concludes. There is quite a bit of debate as to whether the New Opening Project is even canon, but that doesn't even matter. All of the previous movies essentially fit in with the main storyline timeline, though none of them are considered canon.
