According to my inside sources, this is what we can expect to see.
Freak was right about one thing, AHS is coming. Expect it to reveal secrets of the future and the past.
DOOM (The video game) will be represented as a house this year. This is in preparation for the rumored to be greenlit DOOM movie reboot. This will probably release in 2015.
This year will SORT OF have a theme. Universal has apparently stated that it is no longer interested in doing more character based concepts as they think that the general audiences would miss out on these and thus miss out on the scares. Some guests have also said they feel less afraid of something if they understand it, so this is most likely a combination of a few things. No word on whether this decision is permanent or not. This year will be very similar to the last two, however, TWD will not be the theme. Instead, expect to see the park transformed into "the further" and get ready to see your darkest desires come true. This obviously includes a house.
Leaked screenshots have surfaced of the NSO Columbus making a return, although apparently under a different name. Guests will be boarding the Sulaco from the aliens series and for the first time they will be able to take aim at the creatures. Guests will be armed with airsoft replicas of the m41a pulse rifles and will go on a bug hunt. Sounds like it could either be based on disney's scrapped "Nostromo" project or "terror-werks." This house is suspected to be pulsed and extremely intense, but I haven't heard it referred to as an "extreme house" as of yet. This is also expected to coincide with a new dlc package or a new game. Either dlc for "ALIENS colonial marines" or a new game in the franchise. This house is also confirmed to have an RFID scanning system that will link to your account for said game and reward you with bonus XP in multiplayer for each visit. Or it could be one visit per user, unknown as of now.
Maze 1 has been rumored to be a more "meta" project. Guests will think they will be brought on a free tour through a house specifically designed to be lit up house that reveals the "behind the scenes" work of hhn. However, this is false. VERY FALSE. The walls will come down around you as your tour guide gets brutally torn apart and horrors you'll wish you've never seen mingle with more well known threats as not even telling yourself "it's only a haunt" will save you.
The director is somewhat likely coming back. My source says they have seen a piece of concept art for the house. The scene was described as this: "There are two panels, done like a comic book, in a way. One panel has the words "love" written in blood on a wall and the other is a room that's only lit by three projectors. This room is projecting slides, whilst a person sits on a chair in front of it, images being projected on his face. Two other projectors are on either side of him as film reels are being fed through each others slots, tightening their grip around the man and strangling him with said film reel."
Urban legends: Mary is confirmed. Partially, anyways. Mary could be something else but with how difficult it was to get the rights for "bloody Mary" last time, I think Universal decided to say fuck it.
Unfortunately, this is all I have that I can really post here. I haven't heard anything about the other houses or the streets, but I'm sure information will get out whenever... Well... Information gets leaked again, I guess. Freak could be right about the other things, but I think he's just feeding you a line...
It is the day it is, after all.
