Their is definetly an update around the corner, I would say this month, probably at the end/start of next.
Currently digpagerank is working fine and sometime its hit by Google's rest penalty if it crosses the threshold set by G for checking PR otherwise its working fine.
I do Google updates PageRank daily for their employees. For the rest of the world PageRank scoring is exported to the toolbar once a quarter and is now used to keep people who think PageRank = Revenues wasting their time and most others by making posts as to when PageRank updates. To quote myself,
I am fully aware of that. I simply am trying to point out that there are 10,000s of businesses in the world which exist without PageRank. Put the keyboard away walk outside and see how many businesses have a toolbar on their walls whereever you live..... Earning money has absolutely nothing to do with a silly Toolbar Green Ignot. I live in the world of reality...
