I think this also happened some time ago, and the explanation then was that Google must've changed the "threshold". So for ex, whereas before you could've gotten a 5 PR with 30 links, now you'd need at least 50. At least that's how I understood the explanation that was given.

Since it seems pretty widespread, I wouldn't think that all those pages linking to you and to other sites added more links so the value of the link to you decreased. It must've been a change in the algo. So yeah, maybe PR did get a bit stricter this update. Just my opinion.
