Apparently it exists. I'm not a big analytics guy so I don't follow analytics news as closely as I should, but looks like MS has something in the works. It is covered here. The post and comments reveal some really interesting information, such as that the system could possibly give information on Google Adwords tracking and also have age and sex demographics. Don't ask me how Microsoft would pull that off, but it's all there. I think Google Analytics is an amazing tool and the more I use it the more impressed I am, but some competition is always good. At this point I think the Fear-of-Google movement has created enough of a stir that people would be happy to trust a company aside from "the Google", even if it is Microsoft.
