Doubt it, I will take the official confirmation from Sony. " won't pose any new restrictions on the use of PS4 gamers." He
continued, "We believe in the model that people embrace today with
PlayStation 3."
Publishers of PS4 games, then, can do what's already done on existing
PlayStation software: Limit or lock content behind online passes or
redemption codes (or opt out of restrictions altogether), which differs
from Microsoft's limited licensing of Xbox One software."

This is it. They aren't going to impose any NEW restrictions, but the publishers can and have always been able to do whatever they want. The PC is seen as the most open platform, but EA and others have imposed restrictions. But look at what happened with Ubi's PC games, they have backtracked from their previous DRM because it was just unpopular

From what he said Limit or lock content behind online passes or 
redemption codes (or opt out of restrictions altogether pretty much means they won't do anything different is what i take. It's just up to the publishes to do what they want online.
