During Blizzard's annual event, Blizzcon, Blizzard revealed the first expansion for Hearthstone, Goblins vs Gnomes.
The expansion is promised to add over 120 new cards to the game all centered around the mischievous machinists in Azeroth.
Since the initial reveal Blizzard has been trucking away at bringing the expansion to us all as soon as possible (while squashing botters in the game). It looks like the hard work has paid off because the game is making it's official release on December 8, 2014 (yes, next Monday!) for the PC, Mac, and iPad in the Americas. Europe, Korea, Taiwan and China will see the game release December 9, 2014.
