Blizzard's pre-purchase and CE posts say beta runs through October 21, 2026 PST/PDT, and PC Gamer and GameSpot agree. Wowhead's beta guide ('October 22, 2026 CST'), Warcraft Tavern and a roadmap slide reported by Output Lag say October 22. This may just be time zones. Treat Oct 21 PST as authoritative.
