No it actually means Call of Duty Modern Warfare 3 the full title of the game.
No and the Game's title of the November 2007 release is Call of Duty 4 Modern Warfare. If there is a Modern Warfare 4 which is doubtful since there are title confusing problems as a result of the number 4 being used in the name in the first game of the Modern Warfare series it will be released in November 2013
