After a couple of brutal days of speculation and teases, Activision have released this introductory video that sets the stage for Sledgehammer Games' Call of Duty: Advanced Warfare (no Blacksmith, no Modern Warfare 4). The trailer prominently features Kevin Spacey, explosions, hover copters, and well the kind of powerful music we've come to association with Call of Duty reveal trailers.
The footage shown is from the Xbox One version of the game. Speculation has been that the new game would be released just on PC, PS4 and Xbox One, but that has not been confirmed.
Official phrasing is very short and to the point: "Call of Duty: Advanced Warfare envisions battlegrounds of the future, where both technology and tactic have evolved to usher in a new era of combat for the franchise. Power changes everything on 4th November, 2014"
