Want to beta test Diablo III? or you want to beta test Starcraft II? Well, there is no guarantee in this, but the new Battle.net account actually has this option when you are registering a new account.
You don’t need to have any Blizzard games installed or purchased to register yourself to the new Battle.net account. I’ve already registered and opt in to the Blizzard Beta program. Who knows if there really are Diablo III and Starcraft II beta testing!
