I'm not sure if Paranormal Activity will materialize if Insidious was so popular and makes a return. The Hatchet series is up to three movies and Adam Green, the creator, is a huge fan of the event. With Eli Roth doing quite a bit including a new movie he directed, I can see him being involved again. Resident Evil would make sense, especially if Walking Dead doesn't return. Personally, I'd like to see a break from Walking Dead.
