Zeppelins Vendors
The vendors haven't been removed permanently, they will be back on duty once the propulsions issues on boats and zeppelins are fixed. (Source)

Free character transfer eligibility
The realms chosen consist of source realms with the highest sustained queues, and destination realms with the lowest population. The numbers gathered are directly from our data, and depict the realms in most need of these transfers. We will be continuing to monitor all realms and open additional free transfers in the future where necessary. (Source)

Character transfers
Free and Paid character transfers are on a different cooldown, you can use a free transfer and then move your character again by using the paid character transfer feature. (Source)

Wrath of the Lich King
Don't expect WotLK too soon. Even if Blizzard would like to release an expansion a year they don't plan to rush anything for the sake of releasing one a year. (Source)

Night Elf Mohawk !
The Mohawk in the Mr. T advertising was a custom model made specifically for the commercial, there is no guarantee that it will be a new hair style in Wrath of the Lich King. (Source)

World Events
World Events can be a double edged sword, they're a very enjoyable experience for players but they take a lot of development for something only usable once most of the time. there is also the problem of forcing an entire server into a one location and all the performance issues it causes. They aren't ruled out, they just have to be planned very carefully. (Source)
