Cast members had a preview night already so the show is at the point that training and rehearsals are done. many are speculating within 2 weeks (1 now) that other previews might suddenly appear like ap holders or dvc.. I doubt they are going to do a press event again but they might do some additional soft openings (run the show with no warning for whoever notices they are doing it that night).
Now on the other side of things, disney wasn't confident enough to update AK hours late enough to have 2 shows a night (which jungle book needed at first until word got out that it was horrible and then they still ran 2 shows because they stopped using some of the seats with no view). So at least for november which got updated times today (friday) there is nothing late enough for someone to see the tree and the show plus some rides at night. this might just be disney hiding when it's going to open up and bring out all the dinner packages, etc.
