Now that we're in the final saga I have feeling Oda will fumble it. He seems in a hurry and that's not a good thing.
I understand though, he has been writing the series for over 25 years and just want to be done with it.
This is very scarry, rushed plot, I fear that One piece will end like Naruto/Bleach or even worse, since both Naruto and Bleach had at least 200chapters alone for the "final war" arc. And we are supposed to end everything around 3-4years? That is like 120chapters, Oda should stop forcing himself for make such states, it is kinda annoyiing at this point.
Just focus on your story, donยดt cut something out after you spend 25years for all the build up.
I hope he not mess it out, 5-6years are need to make a good story, we could get each year 33-35chapters, in 6years it would be 210 Chapters. Perhaps enough to end all the stories like Elbaf,Vegapunk,Loadstar,Weevil plot,Kid plot,Shanks plot,Blackbeard plot and ofc void arc who is linked to the final war.
