Will there be new dungeons and battlegrounds included in the expansion?
We do have plans to add dungeons and battlegrounds with the expansion, though the exact number has not yet been determined. One upcoming dungeon that we're excited about is Karazhan, also known as Medivh's tower, which is located in Deadwind Pass. Because Medivh has played such a central role in Warcraft lore, we think that a lot of longtime players will be especially interested in seeing what Karazhan contains. As an example of a battleground that will be included in the expansion, we plan on making some of the battles from the past accessible through the Caverns of Time. We'll provide more details as we get closer to implementing this content.

Are there plans for any new instance dungeons in Azeroth?
In addition to the many instanced dungeons included in Outland, the expansion will launch with two dungeons, Karazhan and Caverns of Time, that are located in Azeroth.

Can you tell us more about dungeon difficulty and how it works?
New dungeons introduced with Burning Crusade will have two difficulty options; normal and Heroic difficulty. In order to unlock the Heroic level of a dungeon, players will need to be level 70 and achieve other objectives. More details on these prerequisites will be revealed at a later date. While the challenge at Heroic difficulty will be much greater, the rewards will also scale up accordingly.

Will 25-player-capped raid dungeons also have the Heroic difficulty option?
No. The Heroic difficulty option will only be available in the new non-raid dungeons introduced with the Burning Crusade.

Are older raid encounters such as Molten Core and Blackwing Lair going to be switched to use a token loot system similar to Naxxramas?
We have no plans to adjust the loot system of our previous raid dungeons.
