Being a Mythology buff, this house is pushing all the right buttons for me. An' considering A&D is really proud of this one, I think we're definitely in for a terrifying treat.
An' in the quick interview on the site it does reveal this.
"We’re all very much history buffs here. From South American, Asian and Egyptian cultures, we’ve created a world that mixes of a lot of different cultural mythologies. My favorite creature that guests will encounter is the Amut, which has the face of a crocodile with the mane and front paws of a lion."
So not only we're getting a fun melting pot of mythologies, one of the confirmed creatures is the Egyptian creature Amut. (Techically the spelling is Ammit, though it's also spelled Ammut.) Amut is essentially the "Devourer" or "Soul-Eater" in Egyptian mythology, for when you died and your heart (soul) was weighed with the feather, if it was unbalanced Amut would eat your heart/soul.
Amusingly enough, one of my friends literally drew Ammit not to long ago. So here's a visual reference. (For the house it'll probably be upper body focused with the croc head and lion mane/upper body.)
