Additional information
During this PlayStation 4 live event, Sony announced that their new console would boast 8GB of RAM, a disk drive, a new low-latency controller. Highlights on the controller itself: it has lights that can be used to color-code players, support for jack 3.5mm and a “Share” button.
That is not all because the new console OS would allow to play games while they are still downloading! It would also significantly reduce save and load times.
The PlayStation 4 is a social console: the “Share” button is for screenshots, in-game footage, streaming, etc. That is how you form durable gaming communities.
