Yes, an other Google PageRank update is underway. For example DigitalPoint.com has some data centers reporting a PageRank of 8, when it is currently at a PageRank on 7. Check the DigitalPoint's pagerank at this tool.
The data centers with the new PR at this point in time are: DC: 188.8.131.52 DC: 184.108.40.206 DC: 220.127.116.11
As far as SEO, does this really matter? Again, the visible PR in that toolbar does not mean as much as it did 4 years ago.
You can also see our forums jumping up from a PR4 to a PR6.
