Who do you think the new killer is?

Personally, i think springtrap due to the teaser I saw on DbD's channel having a few to many referances, and think the "hellraiser" file was a troll by DbD

Hellraiser

I dunno, I mean it'd definitely be funny as hell if it happened to be Springtrap, but the whole puzzle thing (Hellraiser has something about solving a puzzle or whatever) and the teaser itself leads me to the conclusion of it being Pinhead.
