EA has confirmed a Battlefront sequel is happening, and that it'll tie into the new Star Wars films, but don't expect to see any Episode VIII references.
Battlefront 2 is slated to launch by March 31, 2017, and EA's CFO Blake Jorgensen affirmed the sequel will use content "from the new movies." But what movies? Everyone made the assumption Battlefront 2 would use Episode VIII as source material, possibly with a campaign focus, but there's a a big problem: Episode VIII doesn't release until December 2018, way after Battlefront 2's Q1 2017 launch deadline.
So where does this leave us? Battlefront 2 could use Rogue One as the source, since the movie is releasing this year, and of course Episode VII: The Force Awakens. But it couldn't be both, especially since Rogue One is based before Episode VII, so EA will have to make a major decision there. Whichever move is tied into Battlefront 2 could serve as the game's major campaign, too. From Jorgensen's words we can assume that DICE wants to focus on the new era of Star Wars for the sequel, just as the first Battlefront was tied into the original trilogy.
