Tigole slipped few details of one of the upcoming instances of World of Warcraft: Burning Crusade expansion. Outland will have 5-man-based instances for casual and hardcore players, allowing you to grow to level 70 at your own pace. However, the instance is still in development and the info was limited. What we do get to glimpse is that small groups are going to get a nice treat.
Tigole: “Tempest Keep is a dungeon in a zone called Netherstorm featured in the upcoming expansion, The Burning Crusade. It’s a max level dungeon with 4 wings. 3 of the wings are 5-person normal, max level dungeons (like Dire Maul is now). One of the wings is a raid encounter.
Keep in mind, this dungeon is still in development so I am a bit reluctant to post information about it, as things are likely to change.”
