Considering how big each game in the franchise is, you'd be forgiven for thinking that Activision would want everyone to know about new Call of Duty games as quickly as possible.
After all, Call of Duty is one of the best-selling franchises of all time, why wouldn't Activision want to get the word out?
For whatever reason, Activision always decides to do the opposite: the publisher keeps each game a secret, and seems to wait as long as possible before revealing it.
The same is true for this year's game: the only thing that fans know about the latest Call of Duty is that Treyarch (the studio behind the original Zombies mode) is developing this year's entry.
However, more information may be coming soon: eagle-eyed gamers have spotted what appears to be a new viral marketing campaign for this year's Call of Duty.
However, this theory also clashes with the idea of Treyarch returning to World War II. Treyarch produced Call of Duty: World At War back in 2008, and rumors circulating throughout the industry seem to point towards a return to the series' roots. Considering the futuristic bent the series has been on for the last several years, going back to WWII would be a huge twist - and one that might not sit well with gamers who were tired of the setting well before World at War was released.
Looking at the campaign as it is, there's no way of telling what the next Call of Duty could be. That being said, if the next game falls in line with the same reveal schedule as previous entries, fans might not be all that far away from finding out what the next Call of Duty is: Activision typically reveals new titles in May, with a larger gameplay reveal taking place at E3 a month later.
So, is Call of Duty returning to the Black Ops timeline, or could it go even further back to World at War? Could it be something entirely new? There's no way to tell just yet, but a proper reveal probably isn't that far off...
