Following yesterday’s delay announcement, Blizzard has now opened up refunds for those who pre-purchased the upcoming World of Warcraft Shadowlands expansion.

In a post on the official World of Warcraft blog, Blizzard yesterday announced the delay of Shadowlands to late this year. A new launch date hasn’t been specified yet, but we do know that the Shadowlands pre-patch 9.0.1 will be arriving later this month on October 13th.
