I just spoke with an employee of Microsoft and seems like they are considering re-releasing the controller. But you must contact Microsoft to get on a list of inquiry so they know how many people want one. If you sign up or get added to the list they will consider making it again depending how many people are still asking for it. So if you want to see it released again, go to Microsoft.com and chat/call the support line. Tell them you want more Information about the controller. Then they should add you to the list of people who want one. (you won't have to pay double the price from retailers like ebay/amazon trying to resale) Hope this helps.
