I've been searching around for one of these also, haven't put much effort but yeah anywhere you look they're sold out. Even if they do get stock in it's usually a big promotion or personally I bet workers let friends/family know about it.
Urban Outfitters apparently had an online sale of them yesterday that sold out in seconds, there's a thread about how people thought it was a scam:

I was in a couple ebgames yesterday, asked both of them and they said they won't get any stock until after Christmas. One of the managers actually got into detail about it, said they've only been given a limited amount since they began selling, like 3 or so every other week. Actually mentioned how they got 3 yesterday and sold them so quickly that there was an incident in the store.
I'd try Toy R us, Walmart, or Bestbuy as the best options. Toy R us was promoting that they were getting a shipment a few days ago.
