But I think the RMAH in D3 can probably tide them over while waiting for the next MMO of blizzard.
Any person putting a CC (or any "real" money) on the Diab-WoW RMAH has to be phucking crazy. The "fake money" AH is currently a disaster and hacking is already rampant in Diab-WoW today. Once "real money" comes into the equation the hackers will be going nuts to exploit the game.
Personally, I think the RMAH is a VERY bad idea, they should just stick to a in-game gold AH where it's fake and use it as a "trading post" so people can (IMHO cheat) buy gear instead of finding it organically in their game if that's what they want to do.
