This game revealed as of a few months ago has gotten some new details: I've actually not heard anything about it before, but it sounds pretty interesting. Disney's lesser known characters rise up and revolt against the top mouse Mickey in an effort to de-throne him.
Be sure to click the links in the artical too, it gets more interesting as you go through them (See: Mechanical Robo Goofy)
The artwork is also impressive, being highly detailed and showing a ruined world under Mickey's rule, though other pictures show you controlling a black and white character. If it looks interesting, leave a comment.
