Battle.net Desktop App

Battle.net

Blizzard has finally released their Battle.net "Steam" Client; a launcher for all of their games with what looks to eventually support RealID/BattleTag Chat.

We're continuing the Battle.net®-related testing we mentioned previously. As part of this, we're now inviting beta testers to help test and refine a new desktop app for Battle.net designed to improve the launcher experience for all Blizzard games and streamline the ability for players to get into their games.

If you’d like to help us with the testing, head to your Battle.net Beta Profile and opt in to at least one of the game universe beta tests (if you haven’t done so already). We’ll be inviting players to the beta test in waves—if you’re selected, your Battle.net account will be flagged automatically and you’ll receive an email with additional details.

For more information, check out the FAQ or visit the beta test forums.

I've also setup a subreddit for anyone interested in discussing it, ^_^.
