Oh my, just because some dude blows a horn somewhere and happens to be dressed up in Viking costumes makes old legends come true? I bet the guy isn't even a true pagan so what could he possibly know?
Apart from that this endless babble of the end of the world is really so last season... and we're still here.
Uuups, is this already a religious discussion? And who is going to play Ragnarök as a tabletop scenario? Now that would be a sight to behold - even if the outcome is predestined and thus rather boring to play, I guess.
