I think this game is a limited exclusive to Nintendo GameCube. I believe this means that the game will be released on other systems maybe a few months after its release on GameCube; however, upon its release Nintendo gets to say, "Buy our system because it has PN 03 on it." I think this is a great selling point for GCN and smart business for Nintendo (obviously, buying the game as a true exclusive would be better, but more expensive).
