Below is the scoop including purported PS4 launch dates, to quote: "Development sources with working knowledge of both next generation consoles have told us that PlayStation 4 will be more powerful than the next XBox, will ship with a redesigned controller and launch by the end of the year in Japan and the US. PlayStation 4's European launch will follow in early 2014.
Sony is set to reveal its next PlayStation on Wednesday February 20th at an event dubbed 'see the future'. Sony Computer Entertainment released a teaser video last night to announce the event. Below, our sources revealed what to expect from PlayStation 4.
Sources close to the hardware have revealed to us that PS4 will ship with a redesigned controller which is the same size as an existing DualShock but features a small touchpad in place of the existing Select, Start and PS buttons. The tech is based on Vita's rear touchpad, and is similarly responsive in use.
