Forum:How long till the end of one piece

OP seems like it will never end. its the greatest manga/anime i hope it dosent end but it still got a long while till it ends.

the strawhats still have to fight the rest of the shichibukai like doflamingo,kuma (when there not exhausted)

the yonkou kaido big mom and the missing yonkou

they have to defeat the admirals and blackbeard which i suppose will be the ending of onepiece

anyone got suggestions of what will happen
