Playstation Universe reports that the next Call of Duty game is called Call of Duty: Blacksmith (at least a working title), and that it's set to be revealed in May (ahead of E3 - no major surprise there). An old rumour on Only SP claims that the game is the fourth entry in the Modern Warfare series. Exactly what Call of Duty 2014 is and what it will be called remains to be seen. But it's very likely we'll have full details next month.
