It all really depends on how well/badly the upcoming movie does in the box office. The last one did fairly good, but suffice to say that if there is no significant increase in box office sales for Percy Jackson: Sea of Monsters, it is probably going to be the last movie we're going to get (at least for a while).

Logan Lerman is not a really famous actor, nor is Alexandra Daddario (as of now). If, however, the new movie is a commercial success, it is safe to assume that we're going to get a slight bump in the amount of users, but I doubt it will be anything major. For us to have problems due to the movies, they would have to achieve The Hunger Games (movie) like popularity, which I really don't see happening (at least with this one).
