If EVER there was a time for filler in any anime, this has to be that moment, right! I REALLY hope Toei gives us just...SO MUCH filler to properly flesh out the post-Wano comedown that Oda blatantly skipped. Give us a decent name reveal and redemption for Otama; some kind of atonement from the people of Wano who lived well under Orochi at the expense of everyone else; Zoro visiting Ryuuma's grave; proper burials for the two scabbards we lost (good ol' whatsisface and whatsisotherface); Momo's decision to go against his father's wishes; set up some new Daimyo + general post-Kaidou Wano reconstruction plans; oh, and, no big deal, whenever you have a moment to get around to THE FREAKING WELCOME PARTY FOR THE NEWEST MEMBER OF THE STRAWHATS!!!
Ahem. I mean to say: Lots that can be expanded on that can meaningfully add to the story. Here's hoping.
