You can expect Electronic Arts to discount Star Wars: Battlefront II at around the time Star Wars: The Last Jedi hits theatres, EA CFO Blake Jorgensen says. The thinking is that interest in the new movie will elevate the profile of Star Wars overall, and with a lower price point, that could help Battlefront II sell a ton of copies.

During EA's earnings briefing this week, Jorgensen pointed out that the company did this for 2015's Battlefront, discounting the game to piggyback on the hype surrounding Star Wars: The Force Awakens. It seems like that worked, as Battlefront shipped more than 14 million copies, becoming one of the most commercially successful Star Wars games ever.
