Well they revealed that some characters won't be able to return due to the 3DS space. They state they will try to get every character they can into the game.
I'm going to try to give you all updates on Sonic Lost World and Super Smash Bros for WiiU/3DS. So always check to see an update about the upcoming games.
I have been working and thinking about Episode 5 of my series for a while. I haven't been able to really do much with it because I've had to get ideas and I had to wait to get some characters. So I'm sorry for the long wait if you actually like and watch my videos. But anyway I'm hoping Episode 5 can be started and completed in the next couple of weeks. That's the shortest time I can get it done. Stay tuned to my channel.
