Blizzard has announced the release date for Hearthstone's upcoming "Whispers of the Old Gods" expansion.

On the official blog, the company announced it will start rolling out April 26 in the Americas, and April 27 in Europe and Asia. The Old Gods expansion will include 134 new cards, including four titular Old Gods. Logging in during the launch period will net you three free packs, including the old god C'Thun legendary card and two Beckoner of Evil minions.

The Hearthstone team is putting on a livestream this Thursday at 10 AM PT, when it's expected to reveal more of the remaining cards. So far it has revealed roughly 70 of them, and you can read about all but the very most recent in our ongoing weekly card reviews. 

Another signfiicant date next week is April 24, after which the charity hero Khadgar will no longer be available to benefit the World Wildlife Fund (WWF).
