The commercials are pretty good especially the Japanese one. Show the controls, how easy they are, and what the game looks like (most important). Hopefully those that like how the game looks won't be scared away now with thoughts that it would be to complicated. Just one remote, direction buttons to move and two other ones to shoot and jump. Very simple.
Now only if 3rd parties would actually follow this model for their rare commercials.
