I have been itching to have a page rank update after its last update in February 2013 especially that I have bought a new domain somewhere in May 2013 knowing that Google is updating the SERP’s every three months.
But unfortunately the Google’s head of search spam, Matt Cutts, announce in Twitter last October that there will no PageRank update this year. This means that update will surely come next year but none of us knows when it will happen.
In the meantime let us all focus to put more quality content to our blog while we are waiting. Although there’s no definite evidence how they give grades in every site it's still best that your site was caught updated and have interesting posts to ensure that you’ll get the Page Rank you are aiming for.
Anyway below is the history of Google update for your references:
