As far as I know the lightsaber is just used as a weapon. I.e. think about the other Star Wars games.

I have feeling that it will be played the same way as Zelda (swishing the remote to hurt others), and the upcoming new Dragon Quest (slashing). JUts instead of a sword you'll be in control of the lightsaber.

Also don't forget about lego batman and indiana jones coming out in the end of the this year/next year.

Woot!
