Here’s a card we’ve been dying to play: the closed beta test for Hearthstone: Heroes of Warcraft has begun in the European region!
During the closed beta test, we’ll be inviting a range of duelers from our opt-in pool (along with folks from press and fansites) to try their hand at Hearthstone and let us know what they think. There’s no NDA during the beta, and we’d love to hear all about your epic victories, watch your live streamed matches, and see screenshots and videos sharing your experiences with the game. Please note that Hearthstone is still in development, and what you see and play in the beta test isn’t necessarily representative of what to expect in the final game.

True enough, that's one of the ways I tend to make sure, by not following links and logging into the actual site itself. At least that way you can be 100% sure where you are.

Looks like some people managed to get a key already last night. There's also slowly keys being handed out on Blizzard CS Twitter, more to come, and supposedly the BlizzardCS ffacebook will have something happening later today as well.
