But we really can't be sure of anything this soon with such little information being said about this upcoming movie. Just about anything could happen. Most of our character assumptions could be completely wrong. O.o All we can do is wait and see.

Considering Shadow's big popularity, at least one of the movies should focus on him. Otherwise, it won't please that many Sonic fans. Knuckles, I'm sure is going to be in the trilogy, since he's one of Sonic's very first rivals. Both Knuckles and Shadow are Sonic's biggest rivals and it would be a shame if they don't get included. Eggman is obvious. I'm expecting him in each of the movies. I don't know if Rogue should appear? If one of the plots is connected with searching for Chaos Emerals, then I'm guessing she might make an appearance then. After all, stealing is her specialty.
