Not 'til 2013 now :(
IMDb has September 2013 as the release date (pushed back from 2012). It's already in post production. Maybe they don't wanna compete with Grave Encounters 2, Paranormal Activity 4, etc this fall. Though they will most likely have Insidious 2 and PA5 next year, depending on when they are released.
