Blizzard's hope of launching Hearthstone into open beta sometime this month, it appears as though bug-catching, card-tweaking, and fine-tuning have gotten the better of the team. The studio today announced that Hearthstone's open beta has been delayed to ensure the game is "ready for wider testing."
According to Blizzard, Hearthstone's open beta is still "very close." Blizzard tempered the bad news with an announcement that it is expanding the closed beta substantially; everyone who opted in before December 16th, 2013, should have received an invite. If you haven't yet opted in, you have until January 7th, 2014, to sign up.
No further card data wipes are planned as Hearthstone edges its way to launch.
