One day I counted all of the scenes with lightsabers in them from all 6 movies - from memory. The ignition count is probably accurate. It's amazing the extent to which they relied on the lightsaber in Episode 3. And it's not like they used it in inventive ways, like cutting through a blast door. It's just lightsaber battle after lightsaber battle. I hope that the lightsaber is used in cool ways in the new movies. For example, a Jedi falling off of a building or spaceship in the atmosphere could use it to arrest his fall by slicing into the building or spaceship on his way down. During a lightsaber battle, one of the combatants could deactivate the lightsaber for an instant, allowing the enemy's blade to fall through it, then reactivate it in their stomach. Length adjustments during battle could also change the dynamic, or using the Force to levitate it while activated. Or using it while on a speeder, slicing through enemy after enemy with abandon.

Of course, the best idea would be to find something more interesting than lightsaber battles to occupy screen time.
