We haven't gotten any characters that we didn't already know about from the original datamining and trailer yet. Blue, Lyra, Hilbert, Hilda, Elesa, Caitlin, Glacia, Grimsley, Rosa alt, Siebold alt, Lance, and Cynthia were all known. That means that before we get characters like Falkner, Sidney, or Dawn, we're going to get

>Leaf
>Nate
>Ethan
>Jasmine
>Valerie
>N
>Kukui (Team Professor?)
>Oak (Team Professor?)
>Sycamore (Team Professor?)
>Silver (Team Rival?)
>Wally (Team Rival?)
>Hugh (Team Rival?)
>Cilan (Team Striaton?)
>Chili (Team Striaton?)
>Cress (Team Striaton?)
>Palmer (Team Frontier?)
>Lillie (Team Aether?)
>Gladion (Team Aether?)
>Lusamine (Team Aether?)
>Sabrina (Team Fashion?)
>Fantina (Team Fashion?)
>Archer (Team Rocket?)
>Arianna (Team Rocket?)

>Diantha (story Champion?)
>Red (Gen I)
>Cheren (BW)
>Grimsley (alt)
>Cynthia (Kommo-o)
>Elesa (BW)
>Misty (FRLG)
I assume that all the characters shown together in the trailers or on the title screen will be appearing in the story as their own teams. They can still appear in banners like Blue, Hilbert, Hilda, Elesa, Caitlin, and Grimsley did/will. Any other story team predictions?
