Edited sentence: " Wii will be released in the United States, its launch territory, on November 19 2006, which means that if Miyamoto holds true on this statment, Super Mario Galaxy will be released before the end of May 2007.However, it would not be a surprise if the game does not see release until after May 2007, since Miyamoto's games often have a tendancy to be delayed numerous times past their original release date
