So, in the latest and awesome episode 325 we finally saw the fight between ace and blackbeard, and in the end of the episode I was surprised to hear the narrator saying

"The fight between those to pirates will be remembered as a trigger to a big event that has yet to come".

I don't really remember reading this in the manga but I think it was there. So, what do you guys think this big event is? Could it be the new age they keep talking about?

(ok now i don't know if its new age or new world but you know what i'm talking about )
