(Image credit: Tom's Hardware) Valve's team controller will be available for preorder here starting at 10AM PT today. Valve’s Steam Controller quickly became a runaway hit, selling out in an astonishing 30 minutes after its official launch. However, Valve is giving its aficionados who didn’t get one in the first wave another opportunity to purchase the controller. The company has announced a new reservation system that opens at 10 AM PT today, allowing eager customers to reserve their own Steam Controller. Having a reservation doesn't mean you've secured your Steam Controller, either. Once Valve initiates the next phase and begins sending order e-mails, buyers will have a three-day (72-hour) window to complete their Steam Controller purchase. If you’re not in the habit of regularly checking your e-mail, we recommend you remain vigilant for the next few weeks, or you could lose your chance to buy a Steam Controller.
