"Real" Pagerank (as opposed to a toolbar guess) has been given to dynamic pages for the first time. Dynamic pages tend to be updated more frequently. That's why I suspect that there's been a major shuffle in some competitive areas. Those areas - like <edit>widgets</edit>, to use the above example - tend to have a lot of dynamic sites for all the different information. Pages "not yet ranked by google" always have shown up in SERPS, but there would have to be an almost exact term match and little competion for it to show up near the top. Now that there are millions of pages with a real page rank that didn't have one before (even a PR1 is better than not ranked, right?) the SERPS are going to be majorly different in those areas.
