Filled with ever stripe of One Piece spoiler you could imagine up to and including the current manga chapter (579) and anime episode (463+).
Eiichiro Oda just recently announced that One Piece is going on a month-long hiatus after chapter 597. So as the manga moves on to the next stage I thought I would be the perfect time for me to reflect how I think One Piece will end. As I have expressed on the blog before I enjoy trying to figure out what the mangaka has planned and see how many of suspicions are correct. Oda plans out his manga enough that I feel this is viable thought exercise because he is not just making up the story as he goes along. Everything below is my speculation but I feel my theories have a good deal of contextual proof and hints backing them up as well. So let us sail to the end of the Grand Line and see what is there.
