Matt Cutts Showed the indication on Twitter Yesterday, He Said It would be surprising to me if Google is pushing anymore PageRank Updates. He Said this in a response to a question that was asked by Niels Bosch on Twitter.
We all were waiting for another PageRank update as it has been 8 months since last Google Toolbar Page Rank update. Seriously guys PageRank is going to be dead soon. We can expect one more update in next year but there are very few chances for that.
Stay tuned for more updates and news from Search market!
