Call of Duty 2021's rumoured development issues, stem from a series of rumours from industry leakers. Well-known leaker Tom Henderson, who has previously leaked details about the upcoming Battlefield 6, stated on Twitter that Activision will be releasing a premium Call of Duty title this year and that “they knew it wouldn't perform that well," with a so called "'recovery road map' [...] already in place.”

I would personally take the DMCA with a grain of salt until more info comes out.
This message was actually posted in response to another Twitter user called Soapkai who reportedly received a DMCA takedown on Discord for posting Call of Duty 2021 leaks (reported on by Zesty - News & Leaks). Those leaks themselves originated on 4Chan and stated that Call of Duty 2021 was going to be delayed due to development struggles. According to the 4Chan leaks, Sledgehammer is getting “sent back to support studio” and this year’s Call of Duty, rumoured to be called Call of Duty WW2 Vanguard, is currently “unreleasable”.
So where does that leave us with regards to a new Call of Duty this year? Well, the 4Chan rumour states that we’re getting a Call of Duty Modern Warfare 2 Remastered multiplayer experience. Activision has obviously not confirmed or denied these rumours, but the fact that it seemingly issued a takedown notice for the leaks on Discord does add weight to the supposed leaks’ authenticity.
