Sega and Nintendo aren’t talking about Sonic returning in Super Smash Bros for 3DS/Wii U. It seems like a no brainer for many, but the two companies aren’t saying anything yet.
Sonic Team’s Takashi Iizuka had this to say about the blue blur joining Mega Man as a third party character in the new Smash Bros.
All we can say is that we also think it would be awesome if he was in the next Smash Bros. So yea, but that’s more of a question for Nintendo than us.
I’m sure Nintendo would have contacted Sega about it already. My guess is that Smash Bros doesn’t release until late 2014 so they’ve got plenty of time to add him later. Perhaps they will work on the core Nintendo characters before adding anyone else. Then again, they’ve already admitted Mega Man is in the game so what gives in regards to Sonic?
Either they really aren’t thinking about putting Sonic in the game or they’re holding out on confirming him. He would have been drowned out by the Mega-Man announcement so perhaps waiting is the best bet.
