The planned Call of Duty reveal leaked early, so Activision thought: hey, why not just fess up and announce this year's game? Call of Duty: Advanced Warfare is this year's game, and it'll be available on PC, PlayStation 4, and Xbox One on November 4th. (And PS3 and Xbox 360, according to Amazon.)
Sledgehammer Games is developing this year's entry, the first to take advantage of Activision's new three year development strategy for the series. As evidenced by the name, Advanced Warfare takes the series into the near-future yet again, with soldiers warring in mechanized suits.
According to Activision, "battlegrounds of the future" will change the series, as "technology and [tactics] have evolved to usher in a new era of combat for the franchise." But don't worry, the more things change, the more they stay the same--look at all those explosions!
