BlizzCon 2015 starts in a couple of days — Friday, November 6th, to be exact — so Blizzard has published an event roundup to help you make sense of all the dev panels, e-sports events, and costume and talent contests.
If you can’t make it to the show, there is some freely available content viewable via livestream which includes the opening ceremonies, the WoW arena world championship, the Hearthstone world championship, the Heroes of the Storm world championship, and more.
