The "French" language will survive in Quebec as long as there are laws to protect it. Possibly a better question to ask is how long can the English language remain in Quebec, as English speakers are the minority here. How can it survive if people aren't required to provide service in English, when there are laws restricting who go to an English school, when it's use on signs is regulated? Road signs are all in French, many bus drivers have been known to answer in French when someone asks them something in English. And now the provincial government wants to make it so that trials do not have to be offered in English (the Canadian Charter of Rights and Freedoms allows you to be tried in your choice of either official language) unless the prosecution wants to, so much for being able to defend yourself.
That said, what is spoken in Quebec isn't really French, it's umm.. corrupt, and the Academie Francaise probably wouldn't be too happy with it.
