Blizzard shifts from Diablo 4 expansions to seasonal stories leading into Diablo 5

Blizzard announced at BlizzCon that Diablo 5 will launch in 2029, set a century after Diablo 4 in a Sanctuary overtaken by Diablo, with no further expansions planned for Diablo 4. Diablo game director Brent Gibson said the team is focused on Diablo 4 seasons and transitioning to Diablo 5, having concluded the "Story of Hatred" with Mephisto. Seasonal content will bridge the narrative toward the apocalypse, with story direction flexible based on fan reactions. Gibson indicated Diablo 4 support will continue "for a very long time," citing Diablo 2 Resurrected's recent new class as evidence of Blizzard's commitment to the franchise, though the exact form of future support remains unclear.
