World of Warcraft: The Burning Crusade Q&A

GameSpot had the chance to sit down with World of Warcraft lead designer Jeffrey Kaplan to learn more about the MMORPG's upcoming The Burning Crusade expansion pack. A bit about socketed items:
Q: What sort of system will The Burning Crusade have for socketed items, and how does it compare to the item-socketing system in Diablo II: Lord of Destruction?

A: The system will be fairly similar to that of Diablo II, along with some nuances that will make it unique to World of Warcraft. For example, we plan to introduce a new type of gem that grants bonuses that depend on the other types of gems your character is using. In addition, players will be able to overwrite gems, but at the cost of the gem they are replacing.
