Quebec's crisis has been outgrown in a way, but mostly because young Quebeckers are more interested in securing a financial future than they are in soverignty.  That movement was akin to the young baby boomers "finding themselves" in the 60s and 70s; just as there are few hippies left, there are few Quebec nationalists -- and those that remain are mostly aged.

The other thing is that I believe the majority of francophones have come to realize that without the ROC as a buffer zone, their language and culture would be more emperilled.  The federal governmnet props up Quebecois culture almost as much as the provincial one does -- official bilingualism is national, federal funding for Radio-Canada, and more rights to self-determination than any other province.  Were Quebec to go it alone, assimilation pressures would be greater.
