Here's more Diablo III news, as the game's website has word that the real-money auction house is now live for the Americas region of the action/RPG sequel, allowing the sale of in-game items for cold, hard cash in the form of the U.S. dollar, Australian dollar, and Mexican peso. They say the launch will follow for other currencies in the Americas region as well as the European game region, as they are staging the launch to try and keep things running as smoothly as possible. To that end, this involves equipment only to begin with, and they will roll out commodities trading in future. They outline regional restrictions on how this works, and remind us of the recently announced requirement that an authenticator be used to by real-money auction house users.
