Blizzard used BlizzCon to reveal a spring 2029 release window for Diablo V, alongside confirmation that an animated Diablo television series is in development with Netflix. The announcements matter as they signal renewed long-term investment in the franchise following Diablo IV, and suggest Blizzard is expanding its games into television, following persistent rumours of a Diablo adaptation dating back years.

Details remain scarce for both projects: the Diablo V teaser only hints at continuing the story after Diablo IV, while no release date or animation studio has been named for the Netflix series, which Blizzard says will see "Sanctuary's darkness" spread further. A 2020 report had previously suggested an anime-style Diablo series was in preproduction with Netflix distributing. Blizzard also teased similar screen adaptations for its other major franchises, Overwatch and Warcraft, though without further specifics.
