The expected event from the opening ceremony of BlizzCon came to pass when Blizzard announced the next expansion for World of Warcraft.
The setting is a renewed struggle between the Alliance and the Horde. Initial details and the cinematic can be found on the Battle For Azeroth site now up.
In what I can only call a surprise turn of events, given the company’s outlook up to this point, Blizzard also announced that they were working on a restoration of vanilla WoW.
Called World of Warcraft Classic, there were no details presented as to when or how this might come to pass, just that it is now officially a work in progress. We shall see what comes of with this. But they have a video at least.
