September 14, 2026 — BlizzCon 2026 may be the last one for a while. Game journalist Rod "Slasher" Breslau — historically close to Blizzard — said the show probably won't return in 2027, pointing to 2028 at the earliest (per Icy-Veins).
TL;DR
- Claim: no BlizzCon before 2028 (Slasher, via tweet)
- Status: not an official cancellation — Blizzard has said nothing on 2027 dates
- Context: fits the industry drift from annual conventions to digital events, plus Blizzard's long-dated slate (Diablo V Spring 2029, StarCraft 2030)
- Blizzard promised more on several games, including WoW's Last Titan expansion, early next year
Bottom line
Annual BlizzCons are likely over; expect longer gaps between bigger shows, with announcements shifting to digital beats. The preview scorecard stands as the record either way.
