Unknown, since there has been no official information from SEGA about a second Sonic Heroes.
Yes they is going to be new teams in sonic heros 2
Supposedly, yes.
sonic heroes 2 is real. in this game is new team. new characters: silver, blaze, shade. the game is coming 2012
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.
Exactly the Same, but just in a higher resolution since the game is newer. Hope i Helped.
There Sonic Generations
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.
probably not
I heard its going to be called Mario and Sonic in the winter games
They are making Sonic Colours for Wii and DS as well as Sonic the Hedgehog 4.
There has been no proof on a new Sonic x,so no.
probably not
