Bornakk has confirmed that the next wing of the Icecrown Citadel, Crimson Halls, opens in two weeks. The next one after that will be Frostwing Halls.

According to Blizzard:

The Crimson Hall contains the leaders of the San'layn, undead blood elves who oversee the Scourge's operations throughout Azeroth. The blood-princes Valanar, Keleseth, and Taldaram were raised into undeath by the Lich King to avenge themselves while protecting their blood-queen, Lana'thel.

Plagueworks has just opened today, starring Professor Putricide and his buddies, Festergut and Rotface. And before you have time to yawn at the lack of new challenging content, the next wing will be open.

We'll keep you updated on any details, as usual.
