Movie theaters aren't going anywhere anytime soon. Despite what damage pirating HAS done to the movie industry, it isn't irrecoverable or unsustainable. Films still break box office records for opening weekend and total overall gross all the time, such as The Avengers, Avatar and the Harry Potter and James Bond franchises. One shouldn't underestimate the experience that most people have of watching a movie in a dark theater with others. It just carries a more special and magical feeling to it than sitting at home and watching it on a normal TV does, at least the first time you watch it. (I'd also wager to bet that the majority of movies that someone downloads is the kind of movies they're not likely to leave the house to go see in a theater anyway.)
As long as it wasn't the main event, WWE likely wouldn't care either way if the live crowd happens to shit on it. And I'm still banking on Punk/Triple H headlining this year anyway.
