From what I've heard about the Shining, I wouldn't expect King to be in the mood to sign off on something he still has any modicum of control over.
The Conjuring was fully approved until it wasn't. And the house was basically built by the time the legal issues got pushed into licensing agreements. It's replacement sounds... serious. It definitely doesn't feel like a dark comedy house. And it may allow some unique visuals that hadn't been seen yet in a vampire house.
Remember... you have to invite them inside...
