Might as well be true, I remember reading somewhere that Takashi Iizuka said he would like Tails to be a playable character more often, since he was important in Sonic 4: Episode 2, so there might be a game where there's more than only running/flying/burrowing/whatever with Sonic in his many forms. Also, don't forget that Takashi said something about a new Sonic game coming in 2013
