I don't get why every expansion for WoW people emphasize black friday so heavily. Blizzard could release a game anytime they want and it will sell. You know why? Because WoW expansions are required to progress in this game. People will buy it whenever it comes out so they can stay in the current content and not fall behind. Blizz doesn't need to push expansions out on black friday like standalone games because their products user base needs the game. For instance, i can go back to CoD 4 and still find plenty of people playing. How many guilds are JUST raiding BC content like it is progression?
