It will run down Zombie Hunt's old path, as from the looks of things, the maze will be Zombie Hunt without the guns. They have a ramp leading down from where the Timber Tug queue currently is. There's a wall blocking the way but my guess it that it'll be removed so the maze can run down there.
Platform keeps it's previous queue and entrance, Dead Creek goes where the Blair Witch queue used to go then down it's old path up until the IAC area, where it diverts to the right and exits down that path they've built to the right of the area. Blair Witch will presumably queue in the other half of the IAC area and enter from there down to the shed.
