It's business as usual for Activision Blizzard despite Microsoft's ongoing buyout (the deal won't be finalized until mid-2023) and the multiple lawsuits filed against the controversial publisher.
Having said that, Activision appears to have a plan in place for a subscription-based service for Call of Duty going forward. Specifically, as per CharlieIntel, the Activision Careers Page lists unfulfilled roles for what is supposedly the future of the Call of Duty brand, CoD 2.0. The listing describes Activision's plans to move forward with this new era for Call of Duty in 2022, saying that this year "is a stellar opportunity" for the brand due to "an extraordinary lineup of innovations in curated player experiences, multi-platform gameplay, subscription-based content, mobile game development, and a move to always on community and player connectivity."
According to the listing, the newly-hired "leader will extend the CoD brand authentically in ways that engage core audiences and ignite and excite new ones."
