It is quite surprising that there has not been a PR update in the last month, as such I expect it will happen sooner rather than later.
Yes, backlinks have been updated for sites that were made as recently as August. This may well signal that a major PR update is coming soon.
Read more here What’s an update? After you read this it will be clear to all of you what that means. The update done already and performed constantly. Every 3 months Google performs export of the data, so that webmasters can see where they are. The changes in rankings and traffic already there for a while. Don't expect to see your PR going up (in toolbar) and immediately increase in traffic
As you can see my post from page 2 in this tread http://forums.digitalpoint.com/showthread.php?t=1930324&page=2#post14912359 I was 100% right about the minor update- it did happen around September 13-15. Internal pages only. Full major update 30 days after, so 15-18 days from today. Pencil my words
I love these threads , endless speculation and rumour.. I for one am hoping it will be this weekend/end of September but as others have said only G know and all this chat wont add any weight behind their schedule... It will be when it is , not before.. Fingers crossed and best of luck but dont hold your breath.. Tansley
