A random thought I had the other day:
Lucasfilm always made sure to time their dvd releases of the movies with a video game. The '04 OT set hit the same day as Battlefront. RotS dvd hit the same day as Battlefront II. The GOUT's release was the same day as one of the Lego Star Wars games.
Anyway, we know the new Battlefront game is releasing by the end of this year. It would make sense for them to schedule some kind of blu-ray release for the same day.
