I thought since this game is out now, I should bump this topic in saying that I played this game and....its alright. Its not spectacular, its not a steaming pile of donkey shit, its just average but what I can say is that secret rings was more fluid than this game. It plays similarly in design, you are practically on rails(so the camera still cannot turn, which is a bitch) but instead of him instantly going forward, you use the joystick meaning you have free movement. Not only is this clunky but there is really no point in doing this as the camera is still fucking locked. My only guess of why they did this is to implement wii controls for the *sigh* sword fights.
The sword fighting is mediocre at best, its all waggle with no gestures. Unlike most games, however it at least reads your waggling for the most part and it's not broken. The graphics are great for a wii game and it has a nice attention to detail, as do the comic book style cutscenes. However, those same cutscenes are plagued with you guessed it, the highly incapable 4 kids voice actors and the dialogue is corny and just awful. There are many unlockable items in the game and you can play through the levels as other characters with their own abilities, so there is a good amount of replay value. I still cannot bear the fact that sonic is actually using a fucking sword though but the game turned out with better results than I thought, but that's not saying much.
