This seems to be about the end of an era and the beginning of a whole new one. And nothing seems able to alter that course of History.
But I don't think we will see anything that doesn't have some kind of historical precedent. The thing is that nation state is changing. It is fundamental construct of European democracy and way of life. The options seem to be EU getting more power or EU disintegrating and current nation states finding new form. Both in identity and borders. New migration period vs. formation of Austrian empire. Speed of change can of course vary.
Neither seems nice. I never guessed I'd find myself to be conservative.
