I expect they'll have dismemberment as an optional feature, probably off by default so the kiddies don't see it. But really, after Episode 3, the kiddies should WANT to see the lightsaber cut things off
I never quite understood why so many games with lightsabers didn't have dismemberment systems. I remember playing Jedi Knight: Jedi Academy, and its dismemberment system was excellent! Many was the time when I chopped a Sith warrior's arm and head off in one swipe, or cut him in half at the waist. (or stab him in the chest and his body flies apart, lol glitch XD)
Sometimes I'd manage to chop their lightsaber hand off and it would roll down the stairs. It was really cool! But then TFU came along and made lightsabers feel like sledgehammers
All I can say is, the camera style and control responsiveness had better be improved in the second one, because those got me killed a lot in the first game.
