I have three guesses who it can be.
 * Classic Tails, Classic Knuckles and/or Classic Amy will be playable.
 * The game is set on an alternate timeline, thus alternate reality Sonic.
 * The game is set on an alternate timeline, thus alternate reality Eggman as new villain.

Though chances are a brand new character to the roster of disposable Sonic friends.
