Your Questions Answered: What We Know and Speculate About ‘Star Wars Episode VII’ and Disney’s Purchase of LucasFilm
Update: We're listening in to Disney's conference call right now, andDisney just confirmed that Industrial Light & Magic and Skywalker Sound are included in the transaction. It also confirmed a long-term plan of releasing a new feature Star Wars film every two to three years — beyond the planned Episodes 7, 8, and 9.
Let's just see how the next 3 films do. Obviously the franchise has room to tell other stories with feature films and TV series but every at least 3 films every decade?
