So, since we are on break again. If I were to hazard a guess as to what could happen that'll trigger the great war arc that is inevitably coming. Vegapunk is clearly about to tell everyone that the mother flame was used to destroy an island. My initial thought is Oda will have Vegapunk give a high-level summary of the void century that ends with the name of the kingdom that fell 900 years ago. As well as revealing Imu to the world. We have seen that pretty much everyone is listening so if there was a dramatic place to reveal it to the world now is the time. We could also get an extended history from Vegapunk but I'm not too confident on that.
For other thoughts on the chapter. Thanks to Vegapunks message, Saturn ran off and the Straw Hats on the Labophase are free to escape. Not gonna predict how many chapters it will be exactly. But we have to be damn close due to Sanji, Zoro, and Jinbei being the only ones missing. Once the Straw Hats hit the water, they can coup de burst out of sight. With how Luffy has been running with the giants I think they'll drop down really close to where they end up so Luffy can hop on.
We also have the question of Lilith. It has been lost in the chaos, but the plan was to have the satellites help Vegapunk get off the island. Lilith is still with everyone but with Vegapunk dead I don't think she will actually leave Egghead. I can see her staying and using her remaining time to subdue York so she can't do any more damage. Or another activity to make sure everyone gets out.
For the wild card bonuses because there are a lot of moving parts, and it is difficult to see how Oda will tie it all together. Who knows, maybe the giant robot will be the one to hold down the elder that is hounding Luffy. If I were to also galaxy brain this. Since we say Vegapunk hanging out around the giant robot in a trash heap at the start of the arc. I'm starting to think that the "twist" is the main transmission snail is either in the robot or in that trash heap.
Oh and in regards to the cover story. I suppose this is our chance to see if Oda walks back Drake and Hawkins seemingly dying at the end of the raid.
Holy shit I'm gonna be an uncle
Ayyy congrats!
