No they are not that regular nor can anyone talks certainly about the upcoming updates. One thing which is certain is that the power or PR and its impacts on the websites rankings have diminished in the course of time and nowadays you can find a lot of top ranking websites with low PR scores over the net. PageRank is just one of the elements Google considers in order to give websites some ranks.
