New Hearthstone Expansion Announcement coming July 28th, possibly Karazhan?
Magic, mystery, creatures, cards? A mysterious invite for something Hearthstone related has been announced for July 28th at 11pm PDT (7am in the UK) over on the Official Hearthstone Twitch Channel (https://www.twitch.tv/playhearthstone) with an "unforgettable adventure planned”
Fans are beginning to speculate just what this could mean, popular theories are pointing to it being a Karazhan expansion reveal as it seems to tie in with the mystery image and countless feathers are on it which may point to a return from our old friend Medievh (who was the Guardian of Tirisfal and could become a Raven - hence feathers) who was last seen hanging around in Karazhan.
You're invited...to something!
Karazhan was one of World of Warcraft's most popular raids and it's likely to become a Hearthstone adventure sooner or later so let's hope it's sooner!
