I believe the new PR update will follow with new SERPs
I disagree. My understanding of PageRank is that its a live, and constantly changing metric (daily, weekly, etc). The only time WE, site owners and Webmasters see the update is when it propagates to the toolbars we use.
In other words, if you spotted a PR change from 3 > 5 after last weeks update, it may ALREADY be changed to something else. You just wont see it until the next "Toolbar" update, when they refresh the data to the toolbar widget.
