Probably. Every main series Sonic game has featured a new character, as have many spin-offs. Although I don't know ho it will be, I am certain that there will always be a new addition. It is usually a villain that Eggman teams up with.
no It's supposed to be about the last 20 years not the next 20 years!
my brother said there is going to be he said that it was grey and black that's all i know
There Sonic Generations
Sonic came from Sega when they needed a new popular game so they came up with Sonic as a character.
If you mean a sonic x episode, most likely not. Silver is just a game character in some of the sonic games
Originally he was going to be, but there has been no confirmation as to whether or not he will be in the new Sonic game.
Yes Ka-ryo, Shadona and sephorix They will be apearing in Sonic and the Hyprosian knights
Yes they is going to be new teams in sonic heros 2
It is possible as the Sonic series has not ended yet, but information regarding any new characters, is yet to be released.
probably not
I heard its going to be called Mario and Sonic in the winter games
No, Sonic the Hedgehog will never be real. He is a fictional video game character designed for entertainment purposes only, and isn't ever going to be real.
