Blizzard has mentioned that you will be soon able to trade commodities in the Diablo 3 real money auction house. Community manager kaivax has posted that gold trading will be enabled later and won’t be included in the current update.
“The ability to trade gold as a commodity won’t be included in this initial update, but we hope to enable it in the near future. Keep an eye on this thread for further updates.”
This update comes at a time when Blizzard is trying to retain the players after having publicly admitted that the game does not have enough end-game content as they would have liked.
“We recognize that the item hunt is just not enough for a long-term sustainable end-game,” Blizzard community manager Bashiok wrote on Battle.net.
“There are still tons of people playing every day and week, and playing a lot, but eventually they’re going to run out of stuff to do (if they haven’t already). Killing enemies and finding items is a lot of fun, and we think we have a lot of the systems surrounding that right, or at least on the right path with a few corrections and tweaks.”
These commodities will soon be available in the real-money auction house:
