Sony have confirmed to GameTrailers that DRM on the PS4 will be down to the game makers to decide: they don't want to "dictate", they just want to "give them a platform to publish on". And make a fair wodge of cash, of course.
Jack Trenton, CEO of Sony Computer Entertainment America, said:
"There's gonna be free-to-play, there's gonna be every potential business model on there, and again, that's up to their relationship with the consumer, what do they think is going to put them in the best fit. We're not going to dictate that, we're gonna give them a platform to publish on."
Most crucially, he said that ""The DRM decision is going to have to be answered by the third parties, it's not something we're going to control, or dictate, or mandate, or implement." In effect, that means that DRM won't be a problem on first-party games, but it'll be up to people like EA or Ubisoft to decide on a policy for their games.
However, Sony also confirmed that "all disc-based games are available to trade or resell however an owner wants, no matter who made the game". What it seems, then, is that DRM issues will only apply for digital games, much like on the PS3 at the moment. [Polygon via TechRadar]
