Well, they keep saying that but I am beginning to wonder if it will happen. I remember reading this last year, and I sincerely hope so. I t will be interesting to see what kind of story they have, I am still holding out for the hint from the last movie, the life-altering page 47. It has to be some kind of American historical event if it follows the other movie themes, seems to me. Can't wait, come on Disney, get your act together!
I think if they could they would, they crank out sequels left and right but I agree with them that I am sure it is hard to write a story for a film like this. It has to happen for an awesome trilogy!
