It was already answered. Kotaku didn't quote everything Yoshida stated. They later reported that it was already answered and they skipped right by it.
"At a roundtable this morning, 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." (Emphasis added.)"
There will be no difference than what can already be done now. Alice Madness Returns. The original Alice was on disc, but EA locked it away using an online pass, the reason I actually haven't purchased the sequel. Allowing third party publishers to do it, passes the repercussions from Sony to those publishers. Even EA doesn't have the balls to force a used game pass onto customers. Their game would bomb hard. For games that don't sell a ton of sales, there's not going to be a used game pass because not enough copies will get out there anyways and they'll only receive backlash from the consumer.

*edit*
I already know what you're thinking. You were thinking of t he Eurogamer interview where what Yoshida said could have went either way. Not natively being an English speaker, he probably thought what he was saying sounded fine. Since it's been cleared up, twice, a report of it around a week ago in most news sites as well, people don't have to continue saying it's locked down like the Xbox One is.
