That's a stupid thing to say that all swordfighting battles with waggle suck, because there is no resistance. There are games with 1 on 1 swordfighting that are well done and enjoyable. (Sports Champions' gladiator fights and Zelda Skyward Sword)Nope. Kinect/Move/Wii sword-fighting will always suck because nothing happens IRL when swords touch.
There's a limited demo of virtual resistance, but it's going to be a very long time before it's doable full-body at a consumer price point.
And resistance isn't even necessary with lightsabre fights, the lightsabre cuts through everything, so going through hordes of enemies should be as easy as swinging wildly like they do in the movies.
