Sony was not expecting big from Move from day one. According to reports laid by gaming news site Eurogamer, the Japanese game maker was expecting a slow start with the initial sales as Microsoft's Kinect was rolled out in the gaming market.

The firm is now totally relying on the viral marketing or word-of-the-mouth to pump up the sales for PS3 controller.

Sony Computer Entertainment senior vice president, Ray Maguire, said, “Exactly as with EyeToy in the PS2 days, it's a product that needs to be sampled. You need to get your hands on it. You need to understand it. You need to try it.”

The VP compared the PS3 Move with the EyeToy PS2 and claiming that the firm never believed that EyeToy could do so well in the first few days, but expected the sales to soar in due course of time.

Maguire further stated that users only have to buy the product in order to recommend the same to its friends.
