Sony wont have a defined system for publishers, no.

But they dont seem to be ruling out publishers ability to require an internet log in (even in the first instance) for their games, even single player experiences.

"If you buy a used disc from GameStop, you’ll have no problem popping that disc in and playing it from your PlayStation 4. The issue may arise when you try to jump online and play with other players. At that point, a third-party publisher may impose a fee or not allow that."

This isn't enough to rule it out? really?
