Well I think if FaceBook decided to enter the browser industry and put a web browser on their site alongside their page browser. Then they could definatly rival google and over a longer period of time could eventually over take them. However when Google's long awaited OS comes out and people start using Chrome and Google as their home page I bet numbers will jump higher especially if the OS ends up being a success and rivalling Windows.
Google has many cards up their sleeves as does FaceBook. But I don't think FaceBook will over power Google on a regular basis for a while longer.
