Just checked my sites and Google definately did update.
All of my established sites are PR6 or higher with quite a few PR7s. All my nedw sites came out of the shoot with PR5s or PR6s.
The only downside is my PR7s arent in the SERPs….. Go Figure…. Google likes my sites enough to give them PR7s yet they list spammy sites that spawn endless windows and cloak at the top of their SERPs for searchers….
