Playstation 3 and Playstation 4 are getting Diablo III next year. You won't see it on the Xbox consoles due to the way Microsoft is. All in-game curreny wold have to be converted to points, and Microsoft would want complete control over that aspect as well.
Nah it's sooner than that. It's when the player realizes their choices mean nothing when they level up. They sucked all the critical thinking out of the game and embraced the RMT people who exist to scam players.
