They've been sold in the US for months. It's just that they keep running out of stock. Pro-tip for those acquiring one: Set up a website stock-checking script in Cron. The "notify me" signup lags by a lot. I didn't get an in-stock notification until hours after they were in stock. And they were sold out by the time the notification arrived. Fortunately, I had a script running and got mine hours before I got the email.
