The Playstation 4 concept was inspired by the massive popularity of its previous versions, while featuring much more functionalities than any other versions of playstation users have encountered. The first notable feature is the cool, transparent appearance of both the joysticks and the main unit. The transparent area of both elements comprises touch buttons for operating the device and the glossy black round compartment is to place the discs of your choice. Playstation 4 will give the gamer a unique cable-free gaming experience with its Bluetooth 2.0 connectivity. Moreover, the transparent display of the main unit can show thumbnails of different part of a disc and allow the user to select a part by simply touching the respective thumbnail.
