Blizzard is unveiling all sorts of World of Warcraft patch 4.3 details at Gamescom. In addition to the officially announced Transmogrification feature that allows players to customize the appearance of their weapons and armor, Lead Game Designer Tom Chilton told Kotaku that 4.3 includes "three dungeons for five-player instances and a new raid instance culminating in the Deathwing fight."

Our friends over at Wowhead summarized all of the 4.3 announcements that have been made in various interviews. Here's the list:

• Deathwing in 4.3: According to Kotaku: "The Deathwing fight will be the most epic boss encounter to date, including a battle phase that takes place on the massive dragon's back as he flies through the sky."
• There will be three 5-player instances: One will be Caverns of Time: War of the Ancients according to Buffed.de. Wowhead's German localizer said Blizzard indicated that another 5-man will be old content revisited. Wowhead's money is on Ahn'qiraj (AQ20/AQ40).
• There will be a cross-realm raid finder.
• From the Video Gamer transcript, apparently there will be a Darkmoon Faire Island with Whack-a-Gnoll.
• There will be armor customization in 4.3: the Ethereal ability to transmogrify a player's armor, reskinning it to look like other armor in the game.
• Purchasable 100-150 bank spaces for old gear: This may also serve as cross-realm storage or multiple character storage. This is unconfirmed but was hinted at; it makes sense, especially with the name "Void Storage."
