Diablo IV's upcoming 'Waking Nightmares' season will feature a remake of the original Diablo game as end-game content, allowing players to revisit iconic dungeons and face classic bosses like Diablo, Mephisto, and Baal in Diablo IV's art style. Following Diablo V's announcement at BlizzCon 2026, Blizzard confirmed no further expansions for Diablo IV but will continue seasonal support until the new game launches in spring 2029.
