Blizzard Teasing Something Big For Hearthstone

Blizzard has sent an invite for a Twitch stream event next week that it's billing as an "unforgettable adventure."

The Twitch event (on the Hearthstone channel) happens Thursday, July 28 at 11PM PDT. The invitation tells of a "once-in-a-lifetime event that will be full of magic and celebration... Please be prompt, as we have an unforgettable adventure planned." It's signed, "An old friend!"

Perhaps the reference to an adventure is a hint that it's related to the single-player mode.
