Battle.net announces the Reaper of Souls expansion for Diablo III launched in North America at midnight EDT, and is now live. A story on IncGamers has details from Blizzard's launch livestream, which apparently had more technical difficulties than the launch of the action/RPG add-on itself. They have some details on how they overhauled the game, and plans to introduce new competitive features going forward, including ladders and tiered rifts.
