Most of the work that we have been doing on Wrath of the Lich King, which involves vanilla fixes and dungeon work is all also applied to the Outland. The cores are compatible.



Also, all of the performance updates as well get directly applied. We are also looking to re-tune some of the content but not with a great extent. The marketplace will get another, but small, update and the realm might be a part of something bigger in the future ;)
