There has been a LOT of discussion about the Warcraft movie, and the role it plays for World of Warcraft. There is obvious critcism, but there is also a lot of hope. I would go as far to say that it feels like some people believe that the future of WoW depends on the success of the movie, and that Warcraft could regrow the game.
But will the Warcraft movie really have an impact on WoW? Sure some people will be receiving a free copy of WoW, but there is only a limited number of copies available. And I believe that a bulk of those will be given to existing players, and of the remaining copies, some of them will not even be used. And that's before they even log in - we haven't even started discussing player retention yet and how much leveling is "broken" as described by Assistant Game Director Ion (Watcher) Hazzikostas.
Personally, I expect the world to still be very empty, the subscriber numbers to stay about the same and overall the Warcraft movie to have little impact on WoW in a couple of months' time. And that's under the assumption that the movie is a success in the first place.
Or is there something that I'm missing?
