An official “reveal” ceremony will take place on August 23rd at 9AM PDT and live streamed at http://gamescom.blizzard.com/
Some of the speculated announcements surround the next World of Warcraft expansion, an initial teaser for Diablo 4 (highly unlikely at this stage even though Reaper of Souls was first unveiled at Gamescom 2013), remastered versions of Warcraft 3 and Diablo 2 (highly possible since Starcraft Remaster just went live this week), Warcraft 4 (highly unlikely at this time), next Hearthstone expansion.
