Assuming a Mod doesn't delete this, as if it is true; I have a few things.
1.) Blumhouse Mashup can go in a few ways. One way, is similar to a maze series from Horror Nights orlando; of "All Night Die In". It sounds very much like it can be similar to that, but actually using IP's in full unlike how Die In handles it.
2.) I am surprised that they aren't doing another mash-up for American Horror Story, as it would be an easy way to allow the maze to then be fully caught up while not trailing on previous content from the past. Or, so I would think. Roanoke, I didn't watch; so if I were to be at the event, I would either have to watch the season in full, or go in blind.
3.) Evil Dead coming back, is somewhat of a surprise. I think it would be fascinating to see how the original two films are tackled, and if they would try to do a subtle nod to Army as-well, as the three are a film trilogy.
4.) I am not expecting much with Saw. I honestly did not care for the maze when I went in it back at 10. Could I be surprised? Maybe, but I just can't see it being good.
5.) Would the Terror Tram, presumably on the Quartet; include Jigsaw to become a Quintet? I am honestly curious how they would be able to tackle something like that, as all the characters have has equal presences at Horror Nights on the Tram before (particularly Freddy and Jigsaw). Either way, I am interested to know of more on this, if it is true.
6.) Shining and Conjuring are the two I'm most curious if true. There is a lot to pick out from each, especially The Conjuring. Would it be using mainly just the two films, or would it be using potentially elements from Annabelle and Annabelle 2?
7.) I have to not be the only one, thinking that Cult of Chucky will be a Scarezone, right? One would assume that it would make sense, as it is a Universal IP and that there is merchandise to have with a character like Chucky.
...It's interesting. That much I can say. We'd be getting 8 Mazes (counting TWDA), Scarezones, a show, and presumably a mish-mash IP fest on the Terror Tram like from 07, 08, and 09. It could be interesting to see what may happen this year, on a marketing standpoint; as there are a lot of IP's I can easily see in the marketing books for the year.
