I could be wrong, but the way I see it is: Whoville/Entry to Bates Motel will be Leatherface's area, the Bates Motel area (which had the little clown "maze" last year) will probably have a maze dedicated to Michael Myers (like what they did in 2011 with Ghostface), the trail up the hill and the tree areas before the Bates house will be a campground for Jason, and the War of the Worlds will be a nightmare scene for Freddy.
