Do you need to own the expansion to play with friends who have it
There will be many aspects of the expansion that will be available to all players. However, in order to experience certain content, such as Northrend, or be able to play as a death knight, players must purchase the expansion.
Will there be an open beta test of the expansion
We have not yet determined whether the expansion will require an open beta test. If we do decide to conduct a beta test, details will be posted on the official World of Warcraft website once we've gotten further along in the development process.
When will the expansion be released How much will it cost
We have not yet announced a release date for the expansion set. However, we expect to announce further details, including the release date and price, on our community website in the months ahead. Please stay tuned to www.WorldofWarcraft.com for more information.
Will there be a collector's edition
We have not yet made any determination about whether there will be a collector's edition of Wrath of the Lich King. We'll be announcing details such as this closer to release.
Will a Mac version be available simultaneously with the PC version
Yes. As with all of our games, Wrath of the Lich King will be compatible with and optimized for both the Windows and Macintosh platforms.
What are the system requirements
We'll continue to ensure that the game is playable on a wide range of hardware. However, we have not made a final determination on the system requirements as yet.
Will the expansion be released globally at the same time
We recognize that players throughout the world will be eager to experience all of the new content being added with Wrath of the Lich King, and we will make every effort to release the expansion simultaneously worldwide. However, there's always the possibility that unforeseen circumstances could delay the launch in any given region. We'll share the launch timing with players in each region as soon as the plans have been finalized.
What is the ESRB rating for the expansion
The expansion has not yet been rated by the ESRB. However, we anticipate that it will receive the same rating that the original World of Warcraft received -- "Teen."
