Certain OP YouTubers and theorists and such are saying this is due this being the end of the series and Oda writing it in terms of a “battle Royal” “race to the finish line”
But the chapters without spoiler summaries are literally unreadable these days. It’s like every week or 1-2 chapters we enter a different story and it just doesn’t work for One Piece
Imo, you have to take everything happening as part of a relevant final "saga" now with smaller arcs.
For example, Yonko saga is Zou, WCI and Wano. Technically, from FI if you want to tie back all relevant plotlines. For years, we got this weird back and forth between Big Mom (FI, part of DR, part of Zou, and WCI) and Kaido (PH, DR, Zou, and Wano), with both culminating to Wano.
Now you have to factor 10x the characters to that same effect, except Oda cant do another 400 chapters x10 to tie together all of these major characters with their relevant plotlines to the endgame.
So, oddly, hes structured this new arc as means to just update us on everything as the storyline progresses within an arc, and not by waiting until the end.
Imo, a lot of this will read better as a volume and completed arcs and not weekly. We'll see how it pays off with Egghead
