The sixth game in the Call of Duty series was originally referred to under the working title Call of Duty 6. The official title for the game was first revealed to be Call of Duty: Modern Warfare 2 by Activision Blizzard on December 3, 2008. Activision Blizzard subsequently recanted their announcement, saying any information about the upcoming Call of Duty game was "speculative," and Infinity Ward also asserted that they had not officially confirmed their latest project. On February 11, 2009, Activision Blizzard reannounced Modern Warfare 2 and set a tentative release date for "holiday 2009"
