Games move consoles, not controllers. A Wii Sports clone won't have the impact of Wii Sports, neither would a Wii Play or Wii Fit clone. I don't see any evidence that 3D will move any systems by itself either, although since it will probably be shoved into Gran Turismo PS3 it probably will help a bit.
People are difficult to govern because they have too much knowledge.
When there are more laws, there are more criminals.
