Sony's Andrew House said the new console will create "experiences that surpass gamers' wildest expectations."
Lead system architect on the PlayStation 4, Mark Cerny, said "the development of a next-gen platform started about five years ago" and that it's goal is "freeing developers from technological barriers." Cerny has a history in the video game industry dating back more than 30 years, first with Atari and later companies like Sega of Japan and Universal Interactive Studios.
The pillars of PS4 are Simple, Immediate, Social, Integrated and Personalized. PlayStation 4 supports suspending and reloading play sessions. The console has a secondary chip for uploading and downloading in the background. Digital games can be played as they are being downloaded.
