Blizzard’s post about the upcoming microtransactions didn’t specify which Realm or region it would apply to, except to say not on the Americas or European realm. Today there’s a post on the Korean Battle.net forums that says… it’s not coming to Korea either. (The Korean post is just a direct translation of the original Microtransactions post, concluding with “not in this region.”)
So which realm is getting the “stash for cash” feature? Not a realm, but a country. China. The features are currently planned to go live only in China, which has its own closed Battle.net server system and doesn’t share access with the rest of the Asian Server. Diablo 3 Stash for Cash — China Only.
The rest of Asia and/or the Americas and Europe might get “stash for cash” options at some point, and lots of you guys in comments to the original post said you’d be happy to spend some money that way. There’s nothing official or imminent about that option, though.
Thanks to DrazzlibKun for sending word from Hong Kong, clarifying this issue.
