I don't believe it will be Sonic from Dreamcast or from Sonic Boom.

It might be an alternate timeline Sonic entirely different from Classic, Modern or any Sonic we've had. I'll put that idea out there but I highly doubt it since it sounds ridiculous.

If Sonic's current friends arn't at all playable for the third gameplay element then chances are it will be an entirely brand new character.
