I expect episode VII to smash all box office records. It will destroy the previous Xmas open. Probably be biggest weekend open ever. And highest grossing of all time when the numbers are tallied. Might be the fastest to all time gross.The post-10pm launch apparently briefly crashed both Fandango and MovieTickets.com. Most of the tickets for IMAX screenings on opening night are practically sold out already. I'd say Avatar better get ready to hand over the box office crown by early in 2016.
I think you might consider revising your videogame/movie sales ratio somewhat. For example, Grand Theft Auto V grossed $1 billion in just 3 days. It's a whole new world in the entertainment market.
