^ I could see a GREAT maze being based off of solely The Conjuring 2, especially with the nun, Crooked Man, and Winkins. SO much maze material, if Murdy wanted to he could drag it out between Parts 1 & 2, but I do see where you're coming from with Conjuring (Pt. 1) overlapping themes with Exorcist.
I also believe Murdy confirmed no iterations of Texas Chainsaw coming this year.
