Disney announced they have plans to support this game for the next five years, so a sequel is out of the question -- if they have Gravity Falls, it'll be in the form of DLC, with a specific playset for the series that you'll have to buy along with the GF figures, as is so with every other franchise represented in the game that isn't part of the Starter Pack (which includes Monsters University, The Incredibles, and Pirates of the Caribbean).
