I had an idea for predicting release dates of updates/new products. While individual rumours vary in credibility, accuracy and time from release date, one thing that seems to be common when a new/updated product as we near release is their increasing frequency and credibility, usually ending with a crescendo as we get into the final days and hours. It would be interesting to plot a graph of time against number of rumours for a few recent products e.g. iphone update, ipad, unibody macbook and so on; to see if there is a recognisable shape that could then be applied to an upcoming product. It might be possible to give some kind of probability on whether a product will be released in the coming week, month etc.
