It is now over 8 months since the last Google Toolbar PageRank update, which happened on February 4, 2013. At the six month point, Google told us a "no comment" on why there has not been a PageRank update.
@NielsBoschh asked Matt Cutts, Google's head of search spam, if there would be a PageRank update before 2014 and Matt Cutts said "I would be surprised if that happened."
So for all those waiting for a PageRank update this year, I wouldn't wait. In fact, I'd be surprised if we see another PageRank update in early 2014. Maybe they will do one yearly now or maybe Google will quietly want it to go away and not do anymore updates?
