It's probably going to have that scene with the ground opening, because Dipper is wearing the same backpack (SDCC trailer). My guess is A-plot, Ford and Dipper visit some alien place (with the ground opening looks like a spaceship could land or fly off from there) and for Mabel I have no idea. The story might not mean literal vs the future, but both of their stories revolve around what they're going to do in the future. Obviously it's all theory and probably not right, but it's my guess.
