idk at this rate 2040 maybe 😔
Unless Oda really goes wild, I think we have around another volume's worth of Egghead (10-12 chapters), a Luffy rescue arc like Ace but reversed that's about 3-4 Volumes, and then Wano Act 4 and 5 leading into Elbaf, which would be around 3-4 Volumes as well.
I'm expecting the Wano Cover Series to last until the beginning of Act 4, and set up its events, such as Blackbeard, Cross Guild, and possibly Shiki making moves on Pluton.
Holy fuck.
I hadn't even considered Shiki showing up in the Cover Series. Or at least being teased... nah, if Oda reveals Shiki, it will be in Act 4 or Elbaf.
