Blizzplanet interviewed Richard A. Knaak at Istrocon 2007 in Slovakia. The novel writer discussed details of the last part of Diablo: The Sin War trilogy, and reaffirmed his opinion that Diablo 3 could be in the works.
More novels based on Diablo are planned through 2008-2009, not just from Knaak, but as he said, from other writers. On the Warcraft side, Knaak confirms World of Warcraft: Night of the Dragon and the Burning Crusade Manga, both expected on 2008, will lay the path to the events that lead to World of Warcraft: Wrath of the Lich King expansion pack with Rhonin becoming leader of the Wizards of Dalaran to rally against Malygos - Dragon Aspect of Magic. Malygos will be a 25-man raid dungeon boss. Watch the video interview (Transcript included).
