The Star Wars Battlefront 2 January update is not going to be released this week, as previously announced.

Community Manager F8rge confirmed on the game's official forums that a critical issue has been discovered in the update, forcing the team to push its release to next week. A new build is already going to the usual pre-release checks, so there should not be another delay.
