It appears that as of the time of the post that Google have either completed or in the final stages of completing another Page Rank Update.
As with all events like this there are winners and losers but all I have to say to anyone is that at the end of the day, Page Rank matters damn all in the universal scheme of things, its SERPS that matter and many’s the time I have seen in the SERPS, medium to high PR sites (PR4+) get their butts whipped (as an american colleague of mine so eloquently puts it) by relatively low PR sites (i.e 1 or above).
Here are a few links to how the update is being received in parts Google Page Rank Update Discussion and more detail about this can be found at this Google Info Blog
