If you've been hoping Blizzard would implement a more direct route to Thunder Bluff, you're getting your wish. According to a post by Kisirani in the official forums, "The Zephyr is getting set to transport players between Orgrimmar and Thunder Bluff in an upcoming patch."

The statement was made in a thread by a player saying that Thunder Bluff was too remote to visit on a regular basis. The player asked Blizzard to fix this by adding a zeppelin stop since it's an elevated city, to which Kisirani initially replied simply with "Okay." The Blizzard poster then popped back into the thread to explain that the Zephyr actually will be flying to Thunder Bluff in the future.
