So their policy is the same as the Failbox until they specify otherwise. And ok so I don't have to go online once every 24 hours to check in with big brother, what about every 25 hours? What if I never want to connect it to the internet at all? Seems that Sony snuck in that you now need a PS+ subscription for online play. So what else aren't they saying?
Read the 3rd article from the links above. It specifically states that you do not need internet connection at all for single player games.
