I dont think he will be. Like most people have said, sonic has nothing to do with any mario games. they are just on the same system. It would be like having Samus (which would cool) on their. In my mind they will have 1 or 2 new characters. My guesses would be either Boo or Waluigi. Or they could change the name and call have it be for all Nintendo characters like Melee. Another cool possibility is each player has their own sercet weapon. One thing that would really spice up the game is if you could unlock new levels or characters
