Tails is always travelling with him and Knuckles has a pretty big connection to the Chaos Emeralds, so Sonic, Tails, Knuckles, and Eggman would probably be the only plot-relevant characters.

Other characters will most likely appear but they'd either be side-characters that don't do much or appear for a cameo on a unique stage.
