When will One Piece end?

It has just been announced that after 23 years in publication the best-selling comic series of all time is nearing its end.

So when will the last manga issue of the main One Piece story (excluding any spinoffs and sequels) be published?

This question resolves when Eiichiro Oda (or whoever is named as his successor) confirms that the last chapter of the story has been published in Weekly Shōnen Jump magazine (or whichever magazine is publishing One Piece at the time).

This question will resolve as 'ambiguous' if one of the following criteria are met: Oda (or whoever is writing one piece at the time) decides to split the story in two without clarifying what the main story is (e.g separating the main protagonist and the rest of the supporting cast without resolving all their stories on the same date). Oda dies and two different people begin writing and publishing different endings to One Piece. Oda gives up on writing the finale and no-one writes it in his place.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
