Monty, Miles and Kerry all worked together to plot out the overarching plotline. Monty didn't have all the plans up in his head, and they were lost when he died; they were created by the three of them together and Miles and Kerry have always known exactly where the story was going. The show isn't going to stop until RWBY's story is completed, and even then they've indicated that they're happy to keep making more after the main story is finished if people want it.
