This does seem to be a true update (as opposed to a rollback), as new sites with no previous PR is obtaining PR on the following datacenters. A quick and easy way to check is to use this tool.
216.239.57.99
216.239.57.104
216.239.53.99
216.239.53.104
There may be other datacenters as well, but those are the ones I know about. So, if you care about PageRank (and I suspect more do than will admit) your wait is over.
