Bill - the backlinks have been that way since about Aug of last year - they have never reported all of the backlinks but back then they decided to not show the important backlinks and just show the junky ones in an attempt to stop the purchasing of backlinks
The second factor is that they have changed the way they show results for the site: command which changed last month - they no longer show the 302 sites that are scraping you - that was their answer to the scraping problem
the PR has been rumoured to be going away from the toolbar - they are getting ready to implement trustrank and have a new toolbar ready to release according to the trusted people I know "within"
they have recently (last week or so during the update) also updated the directory to show the new pageranks so those seem to be accurate
