At the Hearthstone announcement we committed to going into beta testing before the summer was over, and the team has been pulling out all the stops to make that happen.

One last point on the beta test: while we’re going to kick it off with a relatively small number of invites, we’re going to gradually roll in more and more players over time. If you don’t get in initially, don’t worry too much, as new players will be brought in frequently. In fact, everyone who’s interested in playing Hearthstone during the beta period will be able to get in when we transition to an open beta test a bit later in the testing cycle. All you’ll need to do is create a Battle.net account if you don’t already have one, and download the client, and you’ll be set to go! No invitation necessary!
Although our top priority is getting the beta out for Windows and Mac, we haven’t taken our sights off the iPad. In fact, the team hit an awesome milestone with our iPad development not too long ago with our first end-to-end test of cross-platform play. One of our team members jumped into the Hearthstone App on his iPad, saw his Battle.net buddy who happened to be playing on the PC, chatted with him and then went head-to-head in a vicious cross-platform duel. For the record: iPad 1: PC 0.
