Because thats the way nintendo works. Introduce something in a game that will be a big selling point for the game, tout it in press releases and previews of the game, then either they pull it from the game, or it never existed in the first place. I'm going for the latter. Examples: Perfect Head in perfect dark, 64DD for the nintendo 64, internet capabilities on the gamecube, all bonds in goldeneye, oddjob and mayday in goldeneye, tons of other things in goldeneye, level editor for F-zero X, mario vs. DK level editor, Stop N Swap in Banjo-Tooie. Thats all I could think of just off the top of my head.
