I can't say this is true, but maybe SEGA is starting to think of better ways to improve Sonic.
(please dont take this the wrong way SEGA, im not trying to be offensive)
Sonic 06
Shadow the hedgehog, Sonic Riders, Sonic Riders: Zero Gravity, Sonic the hedgehog (2006), Sonic Rivals, Sonic Rivals 2, Mario and Sonic at the Olympic Games, Mario and Sonic at the Winter Olympic games, Sonic and the Secret Rings (multiplayer character) Sonic and the Black Knight (As Lancelot) and soon to be Sonic Colours on DS.
Nether he is in super smash bros Vector the Crocodile (if this is the Vector you are referring to in the question) is part of the Sonic The Hedgehog franchise and has made an appearance in Sonic games such as Sonic Heroes and all three games of the Mario and Sonic at the Olympic Games series.
Mario & Sonic at the Olympic Games, Mario & Sonic at the Olympic Winter Games, and Mario & Sonic at the London 2012 Olympic Games do not have unlockable characters. All playable characters are available from the start.
there is sonic heroes, sonic the hedgehog for xbox 360, sonic riders, sonic riders zero graviti, sonic DX adventure, I am not shure about sonic adventure 1 and 2 because a never have played them but i think they do have super sonic too. I think in the sega games there is super sonic too.
Sonic 06
