From most of the replies here, looks like it will be end of September / first week of October.. Thanks for all the info!
No one really know when it will happen but this one seems to be extended a bit from the last one time table wise , so maybe its right around the corner. In the end all we can do is wait for it to happen and then be happy when it does.
check this link it contain the complete history of the google page rank assignment operation dates seocompany.ca/pagerank/page-rank-update-list.html and some of the stuff which i found is below: Google PageRank Update December 31, 2009 – January 1, 2010 First PageRank Update March 31, – April 1, 2010 Second PageRank Update June 30, 2010 – July 1, 2010 Third PageRank Update December 31, 2010 – January 1, 2011
Historically, the PR updates that occur this time of year occur in either August or October. September is one of the least likely months to have a Toolbar PR update based on the history of such things: http://pravalikadesigns.com/pr-updation-dates.html August updates are fairly common, on the other hand. I have to admit, I don't view the June and July micro updates as counting as full updates. So, I feel we're really off schedule now. But, things have been pretty weird since Google rolled out the whole Caffeine project. Also, everyone and their brother at Google seems to be on vacation right now.
http://pravalikadesigns.com/pr-updation-dates.html Code (markup): I saw the word updation in the URL, which is not part of the English language. Doing some research, I found it was listed at Wikipedia and had no choice but to laugh. Look at how it is defined below. Find some better translation software people! Updation is not a word!!!
lol @ updation, but if that list is accurate it's pretty good stuff. TBPR should be coming in 30-60 days based on the 5 year average
