Speaking with Eurogamer, Sony Worldwide Studios boss Shuhei Yoshida confirmed that it will be possible to maintain an offline status, though advised keeping it connected in order to take advantage of the PS4′s capabilities.
Shuhei Yoshida said: “You can play offline, but you may want to keep it connected. The system has the low-power mode – I don’t know the official term – that the main system is shut down but the subsystem is awake. Downloading or updating or you can wake it up using either the tablet, smartphone or PS Vita.”
“Oh yes, yes, you can go offline totally. Social is big for us, but we understand there are some people who are anti-social! So if you don’t want to connect to anyone else, you can do that.”
