Blizzard has announced that it's investigating the possibility of adding microtransactions to World of Warcraft.
In a post on the game's forums, community manager Zarhym explained that no decisions had been made and the new system would only be available "in certain regions".
"We are currently exploring the possibility of adding a way for players in certain regions to make purchases directly within the game," he wrote. "As part of this process, elements related to this will be appearing on the PTR. We’ll provide additional updates on our plans as development progresses."
The post was made in response to a player finding an item on the Public Test Realm for a future patch that grants a "100% XP Buff" from both killing monsters and completing quests and is available through an "In Game Store".
It's worth noting that Zarhym's response suggests only certain regions will be getting the new system, meaning NA and EU may never see it. Seeing as we already have the Blizzard Cash Shop over here and the company has received some serious flack for accusations of double dipping by having both that and a subscription fee, it's likely the new microtransactions are planned for other countries such as China.
