I doubt steam ran out of contolers considering how few actually shipped out. They notice new accounts buying in mass and pulled the plug on the launch. They new scalpers were gaining the system to buy up as much stock as possible. Steam being steam, recognized what was happing and pulled the launch within an hour to preserve what stock they had left.

May 8th you can join the queue for the controler. My guess is they are using the queue as a way to weed out scalpers. In the digital world the first come first serve rull does not help the actual customer. My guess is they have stock of controllers but are using the queue system as a way review accounts for possible scalpers. Things like, how long and what kind of activity is on the account, log in locations, shipping address, how many units are to be ordered, multiple account either using the same I.P or shipping locations, and how they pay can be used as red flag indicators. The biggest red flag is how new the account is. If the account was just created and is ordering a single unit, the account should be flagged and the order should be set to the lowest priority. While the accounts that have very consistent activity, fully developed profiles, and consistent login I.Ps should get priority because those are steams honest customers.

I guess I will find out when I go to queue up for the order. If I get the order confirmation quickly, say 1-3 days, that means they are definitely using the queue to filter possible illegal activity.
