I don't get why people keep thinking Pedro is going to sacrifice himself. He said that he can't die here no matter what, as he wants to personally be there as the Straw Hats usher in the dawn of a new era. He said there is no way he's going to fall there, not "I'm gonna sacrifice myself to make sure it happens".

Rather than a fights, or perhaps along with fights though, a lot of people are theorizing that Sanji will save the day with his cooking. The Straw Hats have NEVER straight up left a place to its ruin, and literally the only way Big Mom can be stopped when she goes into rage mode like this is being appeased with whatever food she's craving. Big Mom killed off a LOT of the chefs when the cake got destroyed, and Sanji is the best cook in the world. They may not be able to get all those ingredients from all those places again, but there are quite a few members of the Charlotte Family that can most likely produce the ingredients that Sanji would need. I'm personally torn on this theory myself, because while it does make a lot of sense for Sanji's character, and for the Straw Hats in general to not  turn tail while innocent people are dying, I'm not sure how it would affect Big Mom remaining a future enemy. Doing this would have to endear them to SOMEONE in the Big Mom Pirates, so I'm really excited to see where this all goes next.
