The stormtrooper with a lightsaber is a human in multiplayer.
Raven has said that the real Saber battles have never been caught on camera well. We've only seen small bits of it.
Duels will go fast if Im uber god and your uber n00b though.
Its not that the gameplay is necessarily fast.. its just JK was rather slow paced. JKII isn't going to be turn based.. so you will need some reflexive skills and hand-eye coordination.
