"The PlayStation 4 does not need to be constantly connected to the internet, president of Sony Worldwide Studios Shuhei Yoshida told Eurogamer following Sony's conference yesterday. The PS4's internet settings are fully customizable, whether someone is concerned about data limits or simply wants to be left alone.\"Oh yes, yes, you can go offline totally,\" Yoshida said. \"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.\"The PS4 has a secondary custom chip that allows users to play games as those games are downloading, and Yoshida said the PS4 will have a low-power mode where the main system is asleep but the subsystem is awake, downloading or uploading content.Players will be able to wake up the PS4 via tablets, smartphones or with the Vita, Yoshida further explained. The Vita will be able to play PS4 games remotely, with the goal of all games using remote play functionality."^^<http://www.w3.org/2001/XMLSchema#string>
