I am a little concerned with the hype, this fossil has been unveiled with a great PR machine behind it, which is targeting the American population.
There are many transitional fossils in the record, and while amazingly close to the root of the primate tree, this specimen isn't likely to be our direct ancestor. The idea of a great chain of being with man at the top is a truly antiquated idea that was annihilated by Darwin, all this talk of missing links and most important finds may be doing a disservice to public understanding of science (even though its still better than watching religious bigots promulgate falsehoods).
