It was also revealed that Xbox One controllers will have a 30-foot wireless range.
Sony has not yet said how many DualShock 4 controllers can be connected to the PlayStation 4 at once. The PlayStation 3 supports seven controllers simultaneously.
Microsoft previously announced that infrared LEDs in the Xbox One controllers will allow the console to detect, via Kinect, which user is holding the input and then match profile information. One Xbox One controller is included with every system, while additional pads can be purchased for $60.
The Xbox One launches in November. Microsoft said this week at PAX that it believes the console is worth $100 more than the PlayStation 4.
