Microsoft has informed GameSpot that it has discontinued the SideWinder line of gaming peripherals, which included joysticks, gamepads, racing wheels, and a voice communicator. A Microsoft representative said the decision is a result of the continued decline in sales of all PC game controllers and the fact that most PC games are designed specifically to be controlled with a mouse and keyboard. The most recent SideWinder products may still be available in retail stores in the coming months, but Microsoft has been working to discount products to help sales partners move remaining stock.
