Dutch gaming website GameCloud.nl contacted the Dutch division of Activision about the name of the new Call of Duty game. It wasn't clear if it would be "Call of Duty Modern Warfare 2" or only "Modern Warfare 2". But once and for all they gave the following answer. Hanan Ansri, marketing assistant Activision Blizzard Benelux: "It's Call of Duty Modern Warfare 2".
Activision just called us and told that there was a mistake, the game will be called only Modern Warfare 2. Apologize for the inconvenience.
