This leak appears to have some legs, given the name of Episode VII. Certainly, if the Force is "awakening", it must be returning to some prior level of potency. The leak claims that with this shift in the strength of the Force, certain individuals across the galaxy suddenly find they can use the Force. As to why or how the Force is getting stronger - perhaps that's related to Serkis's character, and perhaps, just perhaps, how the Sith were able to weaken the Jedi Order and cloud their precognition in the prequels will be addressed.
