Ubisoft has altered the release schedule for the future batch of content that is set to release for The Division, as the focus is now on Update 1.4 to improve the core experience. The Survival expansion was originally scheduled to release along with Update 1.4 but has now been pushed back to a yet unknown time, though it is on track to release in 2016. Following that The Last Stand expansion will now be released in early 2017.
Update 1.4 will address various bugs, improve loot drop relevance, balance the PvP and Dark Zone, balance gear sets and weapons, balance enemy AI, and alter the inventory so things like skins don’t consume space. Update 1.4 will release simultaneously across all platforms, and players are encouraged to make other issues known through the Ubisoft forums.
