E3 is next week, but Destiny 2 developer Bungie is getting things out of the way today by lifting the lid on its plans for the game’s second year of content.

So far, Bungie and publisher Activision have stuck to the same exact schedule they used during the first year of the original Destiny: launching the game in September, then releasing one expansion in December and a second one the following May. For the sequel, there was Destiny 2: Curse of Osiris last year and then Destiny 2: Warmind just under a month ago.
