World of Warcraft: Battle for Azeroth patch 8.1 will hit the Public Test Realm “very soon”, game director Ion Hazzikostas has confirmed.

The game director said as much during his recent Reddit AMA in which he talked about World of Warcraft’s seventh expansion. Blizzard released Battle for Azeroth last month, and the game’s 8.0 pre-patch was released several weeks before the expansion’s release to prepare the game for the content update.
