You better hope not. Because according to the Mayan swimsuit calender, the world ends in 2012. PR update will be the least of your worries. But seriously, heck, I'd like to know myself.
why would we want to guess the next update..and more to the point who actually cares. Theres more important things to worry about other than your pr, try concentrating on your backlinks and seo to improve your serps and stop worrying about the little green waste of time bar.......
Yawn... Predicting, wanting, wishing, obsessing, drooling, or fawning will not make it change any faster or to what you want it to change to... Why do people even care anymore?
It might be nicer to predict when your SERP will go up instead of when your PR does. SERP tends to impact business profits more than PR does
Well, it could be much better predicting about Google algorithm changes or which new techniques are to be offered in the SEO world rather than talking about that unimportant green bar anyway.
