If Blizzard Entertainment’s recent comment is of any indication, it seems that Hearthstone is not going to be left out of the esports equation.
According to a recent Inven Global interview, Hearthstone might get a new patch that adds in an in-game spectator mode. The game’s Lead UI Designer Max Ma said that the game’s replay functionality is also being considered as a long-term plan. “As for the spectator mode, we are planning on allowing players to spectate select tournaments via in-game function.”
The interview was conducted during the same week as the Knights Of The Frozen Throne expansion announcement, so this quote might be more than just pure coincidence.
