This is untrue.
Especially since Sony is on the record stating that the PS4 won't disable used games.
No, it's true
And while its true that Microsoft has confirmed nothing, I trust the sources that the "always online" and "disabled games without internet" rumors are coming from. Not to mention, Microsoft fired an executive level employee for stating his opinion on the matter of always connected electronic devices on social networks. The fact that several sources in the media confirmed that Microsoft postponed their announcement in order to retool messaging about the new console... All of that smoke means fire.
