Motion controls. Now I'm insulting all companies when I say this, not just the Wii, but motion controls are definitely a fad that will only last maybe to the next generation before their novelty wears off and people stop being impressed by how when you wave the controller it shows up on screen.
Now I know what you're thinking, my definition of fad must be wrong because the Wii obviously wasn't just a fad. Well the definition of fad is "a temporary fashion, notion, manner of conduct, etc., esp. one followed enthusiastically by a group." It gives absolutely no time frame for what counts as a fad. So even if it lasts a full generation or two of video game consoles I still think it'll be considered a fad in the end.
