Star Wars: KotOR II Lightsaber Interview

IGN PC has conducted an interview with LucasArts' Mike Gallo and Obsidian's Kevin Saunders, in which the producer and designer talk about the enhancements they've made to lightsabers in the upcoming Star Wars: KotOR sequel. Here's a taste:
Q: In the first KOTOR, you could use some crystals to change the properties of your saber. Have you added new crystals for the sequel and if so, can you give us their names and properties?

A: We have added over a dozen new lightsaber crystals, many of which are more potent than those in the first KOTOR. Ranging from the modest Adegan crystal to the coveted Ankarres Sapphire, most of the new crystals are straight from the Star Wars universe. The types of advantages provided by crystals are more varied than those of KOTOR.

There are even rumors of an exceedingly rare type of crystal that bonds with its owner, becoming more powerful as they do. The bond is so great that the crystal's capabilities and color even vary with its master's alignment towards the light or dark side of the Force.

Lightsabers can also be upgraded with new power cells, emitters, and lenses. These upgrades can be found throughout the game, but, using skills, can also even be created! There are more than 60 possible lightsaber upgrades, yielding over ten million possible combinations.
