Twilight Princess, whilst an absolutely amazing game, was also available on GC so I don't consider it a killer app. I reckon you guys are underestimating the importance of Wii Sports - it's like the public face of the Wii, the game that introduces you to the Wii and the game you use to introduce your friends to the Wii. Such a killer game.
