World of Warcraft got a host of huge updates at Blizzcon 2017. A new expansion is on the way, and we even got a first look at the new cinematic. But Blizzard also made a surprise announcement with very few details: World of Warcraft Classic will bring back the Vanilla experience.

The news raises a lot of questions, and we talked with World of Warcraft production director John Hight to try and answer some of them. While we didn't get firm details for everything, the biggest takeaway is that the team is approaching the upcoming Classic server carefully. There's going to be a separate sub-team made up of WoW veterans working on this version of the game, but how players will access the content isn't quite clear.
