After Blizzard gave their Blizzcon convention a "rez" (trying to keep up with WoW terms) to be revived this coming August, Blizzard promised to deliver attendees a beta key in the swag bag for "an upcoming Blizzard game." Fellow Blizzard followers, let the forum discussions begin!
Blizzard didn’t give any specific game names, but the most obvious and logical choice would be the recently announced StarCraft 2 game. World of Warcraft players will also get a treat by receiving an in-game Murloc costume. Unless Blizzard announces a new game in Blizzcon (ZOMG another WoW expansion!), Starcraft 2 is the likely candidate for the beta key.
So people of Azeroth, continue your journeys through Outland until its time to hearthstone back to your inns and log-out in August. As for the others, go ahead and install that copy of Starcraft back in your computers if you haven’t already, it’s time for some practice. You may need it soon enough.
