Does the Cataclysm Expansion Pack DVD will contain all the content from the Original, Burning Crusade, and Wrath of the Lich King. If it does, is there any requirements to download anything before the 4.0.1 patch. Understandably, there will be required patches for any version later than 4.0.1.
The Wrath of the Lich King DVD came with all the content of the past on the disk. There was no need to download anything before 3.0.
Yes the account will need to have the access/keys to all of the versions. Which is the case for my accounts.
Please post a reference link along with your answer if possible.
