Blizzard's "Diablo III" still doesn't have a confirmed release date, but more details about the action role-playing PC game are starting to emerge, including the announcement Monday that the game will feature an in-game auction house using real cash for transactions between players. There will be two versions of the auction house used to buy and sell in-game items, such as weapons and armor that strengthen players' characters. One will use in-game gold; the other will be based on real-world currency.
