Google Updated The PageRank Finally

Google Updated My Blog’s PageRank Finally!
Well as it took so long this time I thought it will never reach me! Google delayed in the PageRank updates this time….not that only, but they even started by dropping most top blog’s and site’s PageRank without anyone figuring out the real reason for that.
With John Chow google even dropped his PR twice! First dropped his PageRank from PR6 to PR5, then weeks later to PR4….that was weird as no specific reason for that, in my opinion. ProBlogger and CopyBlogger dropped both to PR4…..Even big sites like StatCounter went from PR9 to PR8….and the list don’t end here!
So what is the reason? Some says it was due to selling links, that reduced the pagerank?? Maybe!! But I don’t think that alone as their is still site selling links and haven’t got included in this event!
Well I got my PageRank update at last…..well not so much excited with the PR3 I made, but atleast I thought they won’t update mine, as I can’t view my backlinks with google while it shows  589  at yahoo …. So  it’s  just fine  for  now!!
Any reason for the big PR dropping think?  OR, for google not showing my backlinks?….fell free to comment.
