Beta invites have gone out for the wildly-anticipated hack n' slasher, Diablo 3, to a lucky group of gamers who had opted in via their Battle.net accounts.  If you're like us and haven't received an invitation (Grrrr), there is still hope as more keys will be provided through promotions and giveaways.  Blizzard is allowing beta testers to share their hellish experiences, so expect to see countless YouTube videos and live streams of the game.  Diablo 3 is breaking some new ground for a game of its size and popularity, by allowing in-game items to be traded among other players for real world cash.  Keep your eye on your inbox for a beta invite while we all wait impatiently for the game to release at the end of this year...we hope.
