Blizzard is set to host a press conference at gamescom this year on August 21 at 11:30AM, and that's the only real specifics we were given. Blizzard did tease us by stating that this announcement is "sure to capture the attention of the Heavens, Burning Hells and all the shadowed places that lie between."
Wonder what it can be! Probably related to Diablo III, as it's on the horizon for the Xbox 360, PlayStation 3, and PlayStation 4.
The last time Blizzard gave a press conference was at gamescom 2011 where they talked about World of Warcraft, StarCraft II: Heart of the Swarm and Diablo III. Blizzard won't be livestreaming the press conference, but we'll be there covering it for Destructoid because we love you. We really do.
