Blizzard Entertainment is in the middle of a dense release cycle that runs from a Diablo IV Switch 2 bundle and a new World of Warcraft line in late 2026 to Diablo V in spring 2029. Its most recent story is a Stellar Blade teaser for an EVE Protocol collaboration with Overwatch, with no date or content given.
BlizzCon 2026, held September 12 and 13 at the Anaheim Convention Center, is the spine of the current picture. The convention returned after three years and carried news for Diablo, Overwatch, StarCraft, World of Warcraft and Hearthstone at once. Before the show, Blizzard sold digital bundles for five games from 3,350 yen, and the event itself paired game announcements with music: YOASOBI played the Overwatch World Cup halftime show and LE SSERAFIM performed on the main stage after the closing remarks.
The Diablo line moved furthest. Diablo IV: Age of Hatred Collection was announced for Nintendo Switch 2 with a September 15 release and a September 16 Japanese release, and a hands-on demo at the show ran without lag or stuttering. Warcraft III: Reforged: Forsaken Kingdom was announced on stage and released the same day as a paid campaign of roughly 30 hours, with Patch 3.0 adding a Definitive Edition graphics mode. Diablo V was announced with a teaser titled "Resurrection" and a spring 2029 release, and an animated Diablo series is in production with Netflix.
Overwatch's slate centers on the support hero Doctrine, a limited-time trial from September 12 to September 15, plus reworks that move Sombra from damage to support and change Roadhog's Scrap Gun, and the escort map Watchpoint: Grimsvotn. World of Warcraft: Forever, built by the WoW: Classic team, adds three zones, more than 1,000 quests, nine dungeons, two raids and the Skyborn race, with a November 4 release and a beta from September 17. Hearthstone's Reign of the Black Empire returns to the Old Gods, and the Monk class arrives with next year's first expansion.
Outside its own franchises, Blizzard is opening Battle.net to CD PROJEKT RED: Cyberpunk 2077, Phantom Liberty and the Ultimate Edition bundle go on sale there in late 2026, The Witcher 3: Wild Hunt Remastered arrives September 29, and Overwatch content themed on Cyberpunk: Edgerunners is set for 2027. A Geralt skin for Diablo IV came earlier as a Battle.net purchase bonus. The most recent story is a Stellar Blade teaser for an EVE Protocol collaboration with Overwatch, with no date or content given.
