I wonder if Oda is going to somehow parallel Sanji against the CP-9 in the W7 Sea Train. But now things should be pretty different, on paper at least
Robin isn't going to attack the crew anymore tho, but we can't tell how strong CP-0 is right now, only speculate
They still have a Seraphim whose powers are unknown.. And Stussy might be a problem too
This will be interesting, even Zoro might show up to help if things get messy
