CVG has a good interview here. Mostly because I think it has the clearest outline of Sony's policy on DRM and used games to date.

On policies:
There's been some clarification over your exact policy from Jack today. We understand that third party publishers can still opt to implement some kind of online restriction on pre-owned games?
What he talked about is with the offline portion there's no difference from PS3 in that every game is playable on PS4. In terms of just getting access of multiplayer online, it's now taken care of at a platform level by PS Plus. So our first party titles had the online pass on PS3 and Vita. That we are not doing on PS4 because of that platform level. It's the same for third parties; when it comes to just giving you access to online multiplayer, it's PS Plus going forward.
There are lots of different reasons. One is that publishers are providing the network services. The simplest example is an MMO; you have a huge community and your constantly adding content... It's an online service. It doesn't make sense that a disc gives you access to all of the online service forever, right?
Another example is games that have content DLC included in a season pass. Outside of just giving access to multiplayer, it's at publishers' discretion to come up with a new business model and offer to consumers.
But that's limited to just the online aspect?
Yes.
On being on stage to present:
I was totally excited and lots of people tweeted me to say that I looked so happy. I was happy there, but going in at the beginning of the planning of E3 I said, because it's in English, we have a great presenter who's the head of US development - he did the press conference last year - and he should do it. But people said, "this is the launch year of PS4 - people want to hear from you." Initially I was like "ah!" but in the end I felt great.
On pricing:
Designing PS4 was all about learning lessons from PS3; the system architecture, ease of development, network services... And the cost of the system is a big part of it. So we always wanted to hit $399 and we designed the system and carefully chose out of all the potential inclusions of the core hardware components and we made a system that we could sell for $399.
So we just did what we aimed to do and we were hoping that people would like it. But we were not totally expecting the external factors that kind of helped us do our business. In short, I was very surprised about the announcement yesterday by some other company... In a good way (laughs).
