Patch 2.2.0 is bringing a lot of good stuff to Diablo III, but something bad must come with every good. In this case, it’s a new “platinum” in-game currency that players can purchase with real-world money which can be used to buy cosmetic items and boosts. In other words, Diablo III is getting microtransactions. Blizzard was quick to point out that this was experimental and not coming to the North American or European regions for now.
We recognize that many players have expressed an interest in microtransactions being added to Diablo III. While we may explore this model in some regions, we have no immediate plans to implement such purchases or the aforementioned features anytime soon for the Americas region.
That discontinued real-money auction house is going to start looking really good once platinum trading shows up in Battle.net chat.
