I bet Sega will eventually get around to releasing a new game, but I don't know how good or even improved it will be. What I am sure of is that the game will have good graphics and hopefully it will be released for more than just the Game Cube. I think they should have a game where you can choose to play as any of the characters from the previous Sonic games. The only real problem is that they work on so many other projects it is hard to tell when or if they will ever release another Sonic game.
