Sonic has the potential to become a loved anime, it has no basic story line (DragonballZ), has a fast fella' (Kirby, Pokemon,etc..) and is know all around the world. Also has the extra of being a game!
What I'm waiting to see is some Sonic in kick ass anime. Imagine Sonic with the graphics and anime of Macross Zero, or Wounderful days!
(sonic would be running like hell twoards someone In a 2nd person angle and then the camera turn to show a huge guy that look like It came off Final Fantasy the spirits within)
