Sounds more like the Xbox One policy now. Still, Playstation doesn't have to connect to the internet, but looks like they are the same as Xbox in that they are leaving it up to publishers. What do you think?

So its basically how it is now, great I can live with that. Xboxone has a drm check every 24 hours thanks to the required internet connection so really not the same.
