Earlier quoted context omitted.
They still have two billion dollar opportunities that they are sitting on: 1. An Adsense competitor 2. Video ads These are not wild predictions of possible revenue streams. Facebook has already launched these features to select partners and when they are launched to the public, their stock will jump a lot more.
I am waiting for a good explanation as to why they haven't started an Adsense competitor yet; seems like it would be a goldmine
Facebook is living up to this promise with the way they turned on mobile ads and they are now bringing in over a billion dollars annually. I think they want to maximize on that opportunity first, then turn on another revenue stream after mobile ad growth starts to slow. If they pull this off, they will be Wall Street darlings
