Activision and Infinity Ward are keeping gamers guessing whether 2019's Call of Duty game will be Call of Duty: Modern Warfare 4 or Call of Duty: Ghosts 2. After the chart domination of 2018's Call of Duty: Black Ops 4, Activision is already looking at what comes next.

The long-running shooter franchise and its spinoffs proved they still have a place as 2018's Call of Duty: Black Ops 4 shunned its critics and Treyarch went down a wholly multiplayer route. Whether Infinity Ward decides to follow suit or returns to the tried-and-tested Call of Duty single player campaign remains to be seen, but either way, an announcement could be coming soon.

Infinity Ward Communications Manager Ashton Williams posted on Twitter, sharing a cryptic nod at the studio's next Call of Duty game. The use of a creepy skull and static effect has fans and experts split into two camps over what Williams means. It didn't take long for some to point out the skull could relate to Modern Warfare's Lieutenant Simon “Ghost” Riley and the skull-clad wraparound he is synonymous for wearing.

Others pointed out that 2013's Call of Duty: Ghosts used a skull motif in its original marketing campaign. Considering it's been over five years since Ghosts came to PC, PlayStation 3, Xbox 360, and Wii U, gamers have been waiting for any news relating to a possible sequel. Similar to how Call of Duty: Black Ops 4 moved away from what everyone expected from the subseries, a Ghosts sequel could reinvent itself for a new generation.

Only a select few know whether Infinity Ward's upcoming title will be Modern Warfare 4 or Ghosts 2, but one industry expert is shunning the idea of Ghosts 2. Posting on ResetEra, Kotaku's Jason Schreier warned that Infinity Ward definitely isn't working on Call of Duty: Ghosts 2. Although Schreier doesn't go into detail why, he's known for breaking industry news and usually being right about these things.

This wouldn't be the first whisper of Call of Duty: Modern Warfare 4. Last year, it was reported that Infinity Ward would make its long-awaited return to the dystopian world of Modern WarfareIf the studio is queuing up Call of Duty: Modern Warfare 4, players should expect another best-selling release. Even without 2018's resurgence in Call of Duty fandom, Modern Warfare 3 premiered in 2011 and sold 6.5 million copies in the United States and United Kingdom in just 24 hours. At the time, Call of Duty: Modern Warfare 3 went on to have the biggest entertainment launch of all time.

Call of Duty games are usually teased in March with an announcement in May, but Activision and Infinity Ward look to be moving a little quicker in 2019. Expect to see more of Williams' breadcrumb trail as both Infinity Ward and Activision continue to tease their next Call of Duty title.
