He said it's the consumer's expectation to be able to play used games, and this is also his expectation.
While there's a degree of ambiguity in what's being said, I don't read too much into it. The whole interview with Yoshida highlights a lot of awkward, simple language, which is fine - he and the PR rep are both Japanese - but combine that with Eurogamer looking for very specific responses, and Sony trying to be careful about the flow of information (which is typical for any product launch), and it becomes very easy to read into things.
I'm not saying a season pass mechanism or something isn't a possibility, just that this wouldn't be a source I use as a basis for speculation.
On a related note, has anyone asked about whether games will continue to be region-free?
