The pattern we all seem to be following, I would say it's just going to be re-makes and re-hashed monsters. Universal is making a shared universe, Avengers like, series featuring the 1930-1945 monsters. Dracula, Wolfman, Mummy, Creature from Black Lagoon. I think we'll see a flood of remakes, prequels, and sequels to Nightmare, Friday, Halloween, etc before they go back to the drawing board and start redoing Hitchcock films. It's only a matter of time before they take credit for Hitchcock's works because they made it, "darker, edgier", and all that mess. The 2010's have been dominated by supernatural demons/ghosts.
Even as of late, movies are just stolen ideas from each other. They made, "Lights Out", which was a ripoff of, "Darkness Falls", not to be confused with the new, "Shadows Fall". It's angering when people don't come up with something new.
I'm surprised there have only been a few horror/suspense films that were related to cellphones.
