Does the PlayStation 4 always need to be connected to the internet, I asked?
"You can play offline, but you may want to keep it connected," he suggested. "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."
Are all of those things optional, though? For people who have broadband data limits, for example? They can customise everything?
"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."
