Long time lurker first time posting.
I think the issue with The Conjuring had more to do with the fact that Warner Bros did a maze based upon it for their Halloween thing and less to do with the lawsuit.
They actually had plans to bring Conjuring to HHN this year for both coasts, but due to the lawsuit; it was pulled and Hollywood got Titans and Orlando got Hive.
Honestly, if there are any replacement's, I wish to see original mazes take over that void, so they don't have to spend money on a reused IP.
