Shuhei Yoshida confirms that Sony will NOT have DRM as standard on Playstation 4 and in fact leave it up to publishers and developers to decide.
Sony's game studios chief, Shuhei Yoshida, told reporters that any requirement for users to register a game online in order to play it would be left to game publishers. Sony won't require that."This was taken in a Q&A press gathering with Kotaku.
So this will be like U-play's Drm on PS3 that publishers are dropping. This is not new news, just news that was not picked up on.
