Its also not really a short arc either though. 50 chapters and counting. Itll be around 70 by the 2 anniversary of the arc (late summer). Thats in line with WCI at least, which was 2.5 years and Wano's 140 chapters was over 4.
This is why I dont expect the series to end for at least another 7-8 years. Conservatively, there are 3 solid arcs left after Egghead: Elbaf, Lodestar and Laugh Tale, and those are just safe guesses based on whats next and what we expect fills the remaining island trail.
Even if Akainu, Blackbeard/Shanks, and Imu filled the roles of those 3 arcs, think about how long each of those needs to actually be to justify defeating those people. If we spend 70+ chapters at Egghead and over 2 years just for Kizaru and to showcase Gorosei who may not even be defeated, what does that even say about:
- 3/4 more Admirals
- More Yonko/Mihawk
- The World Government itself
It is frankly concerning to me, but I've been concerned for 15 years, and its taken the last 8 to deal with 2 Yonko and half an Admiral lol
