The team of destiny is going to win after Falco flies Annie and Gabi to the fight. Everyone lives happily ever after because it was a group of Eldians who saved the world. And a black guy. And it's arguable that there is no such thing as an Eldian anymore after Eren's death. The only real questions will be who lives and dies (Levi, Mikasa, Connie, Gabi, and Falco live for sure, Reiner probably dies, Pieck is 50/50) and how long and treacly the epilogue ends up being. Like Mikasa and Connie probably end up married and living wherever Mikasa's mother was from, Gabi gets adopted by Kaya's family, Reiner gets a moment with his mother before he dies, etc. Also at some point they'll reveal if Eren really was just a slave to causality and was going to continue the rumbling until the world was stomped flat or if he had other plans.
