Hearthstone's next expansion, The Grand Tournament, will go live on August 24, Blizzard just announced. You'll be able to start buying packs and using some of the ridiculous new cards then.
Looks like you won't have to wait too much longer before getting some of those ridiculous cards. Just four days. We can do this.
According to Blizzard:
The Grand Tournament card packs will be available to purchase via the in-game Shop on August 24 in the Americas and Europe regions for Windows and Mac PCs, iOS and Android tablets, and mobile phones, and pre-purchased card bundles can be opened upon the official release of The Grand Tournament as well. The Grand Tournament will raise its banners in Asia on August 25.
The announcement came on the Hearthstone blog, and you can read it here.
