Bribe an employee to hide one for you.
I know this next part isn't what you asked but, just in case you can't get one: What are you missing out on? Is there a game that you simply must play or are resolution and frame rates that big of a deal for you? Waiting sucks but if you can't get one, a lot of games will update when do finally get one (or both!) consoles. And a lot of their library will be cross gen. In any case, good luck!
