if this theory is true, this would only mean one piece is only at the half way point in the entire series

It's past the half way mark, but not by very much. Manga chapter 597 was the half way mark according to Oda.

That guys either a genius or some really creative bastard, that's basically something I'd see happening it fits too well together..

Scariest part for me was reading about the chick who reads the future and how she saw luffy destroying fish man island. When I was on fish man arc I forgot about her fortune telling especially near the end. Still needed explanation

I think that guy is a genius, he must have a wall of crazy with string and everything.
