I agree the sabers look far superior to any other star wars game. If you look at one of the e3 trailers the saber battle between kyle and one of the dark jedi looks really cool. When the sabers clash the whole screen is filled with a flash.
The scarring on the walls also makes the weapon feel more powerful and the saber throw looks very effective and easy to pull off.
All this combined with some of the acrobatics you can perform should lead to more lightsaber duels and fewer jousts.
