According to a customer rep I just spoke with, Amazon Germany had by far the largest Playstation VR allotment of Europe (taking into account that the German division is responsible for Germany, Austria and Switzerland), and they actually sold out in 25 seconds. Amazon was apparently surprised by the very high demand in the German speaking market. Especially Austrian customers bought a lot. (Of course they didn't tell me any numbers).
They already spoke with Sony and they will get a second allotment (no specific date was given; if you are on the notification list, you will receive an email beforehand).
