Over the last decade, we've gone from around 40 chapters of One Piece per year to only 32 chapters in 2023. There are multiple factors for this decrease ranging from the Covid-19 pandemic to global supply chain issues to Oda's personal health and more recently his focus being needed on other projects such as the One Piece Live Action series. So far, with 2024, we seem to be back on track with his typical 3 chapters to 1 break schedule, but nothing is certain.
Will be resolved upon the release of the final chapter of 2024.
A quick calculation: One Piece has been around for 27 years. In that time, in only 5 years has the number of chapters strictly increased from the previous year (namely 1998, 2011, 2012, 2016, and 2021). This suggests that the probability should be about 5/27 = 18%.
