IGN interviewed Tom Chilton to discuss World of Warcraft: Cataclysm patch 4.3.
Tom Chilton revealed a few more details about the Deathwing encounter. Fan rumor set the Deathwing dungeon to be in Outland at the known Deathwing Lair (Warcraft II: Beyond the Dark Portal) or in Blade’s Edge Mountains (World of Warcraft: Beyond the Dark Portal by Aaron Rosenberg/Christie Golden).
Curiously, Tom Chilton says the Deathwing encounter starts at the Wyrmrest Temple:
“”The fight takes place in multiple different environments, you’ll actually potentially get loot at different points in the encounter so it’s broken up into larger scale overall. Players will start at Wyrmrest Temple and then eventually it progresses to players fighting on [Deathwing's] back flying towards the Maelstrom, trying to wrestle him to the ground, basically.”
Chilton talks about the Transmogrifier and Void Storage features and wraps up with debunking [?] of Mists of Pandaria being the next expansion. His term was: “wildly overhyped.” — Source: IGN
