The PS3 is able to support up to seven controllers at once. However, before you start criticisng the PS4, it is worth mentioning that there were very few games that took advantage of this feature.
The PS4 will ship with a single DualShock 4 controller – colors available will be classic Jet Black, Magma Red and Wave Blue. The retail price for DualShock 4 controller will be around £54/€59/$59.
The Xbox One, on the other hand, will be able to support up to eight controllers.
