Our friends over at IGN did an interview this week with Infinity Ward multiplayer design director Joe Ceocot, and one of the questions asked was about how, and if, Battle Royale would fit into the upcoming reboot to the Call of Duty: Modern Warfare franchise.
While he didn't rule out the possibility of Battle Royale coming down the road, even stating he was a fan of the genre, it currently "isn't the focus" of the multiplayer development.
We really focused on Modern Warfare, authentic and gritty, realistic weapons, and it’s a different experience. It’s really...just about pulling back to Modern Warfare and keeping that pure.
The market for Battle Royale games is somewhat oversaturated, and interest in developing new games that will ultimately fail to complete with the big names of PUBG and Fortnite mean that the genre is starting to slow down a bit.
Black Ops 4 had a battle royale mode, Blackout, but Cecot went onto re-affirm that Modern Warfare is a totally different flavour of game, wanting Modern Warfare to be "authentic and gritty" with "realistic weapons" and a different gameplay experience.
So while it seems that the possibility hasn't been ruled out altogether, it does seem unlikely.
