Rob Pardo, chief creative officer and go-to guy for Hearthstone announcements, has a whole lot of news for us involving that game. But one of the most interesting (especially for people who aren't in the closed beta yet, but who want to be) is that, if you haven't gotten into the closed beta, you won't have to wait much longer. Pardo announced that, yes, Hearthstone will have its open beta "within a month... although, it's Blizzard time, so maybe January".
So if you're desperate to start experiencing Blizzard's entirely online TCG, take heart. You will have your chance soon enough. Literally Blizzard soon. Rob said so!
