Do you think his breakdown of the final arc, as related to Wano, implies that it will be right after Wano or after finding One Piece?
So the reason I said it was pointless is because it's kind of hard to tell even in Japanese and I can't really add much to what the translation posted a couple pages back said.
Right now Wano Country is heating up BUT
If Luffy safely sets sail from Wano Country
Basically means a wordly development (世界=sekai=world), (的=teki=kind of means like? For instance if I added 的 to a kanji for say Japanese it would mean that something is very Japanese) and 展開=tenkai=development.
誰も読んだ事ないような大興奮、 One Piece 史上最も巨大な戦いを描く
Then it's literally the most gigantic (巨大= kyodai=gigantic) battle (戦＝tatakau=to go to war) he's ever written will take place, followed by hyping it as "interesting" with two exclamation marks. The use of 戦 is kind of interesting, cause it means to wage war where something like ikusa or sensou is the more usual writing of war in my experience. Idk if there's anything really worth reading into in that or not. I tried to break down the first more important part so people could look up any phrase for themselves but I'll speed through the rest. He says he wants to readers to know that the story is properly/ ちゃんと heading towards it's conclusion, which I bring up because I think it kind of seals the deal that we're actually debating Shueisha's marketing tactics more than any finite road map in Oda's head.
To end with some more conjecture, I think it might be useful to not think of the war as on/off switch with no return and no room for other less related arcs. For all we know he could be saying that if Luffy safely left now he could be caught up in some crazy stuff, but it may be concluded (for the time being) by the time he reaches Wano and all he can do is continue his journey. Given the writing of the story I'd expect a war between the WG and Revolutionaries to happen and make some headlines but it won't be till he finds One Piece that the actual war explodes into a world war.
