The Call of Duty Profile login site and account management site appears to have gotten an update today. The site now lets users link their Blizzard Battle.net account with their Call of Duty Account.
This could suggest that Call of Duty for PC could be soon available on Blizzard’s Battle.net going forward. Currently, Call of Duty games for PC are only available on Steam.
Activision first started bringing their titles for PC to Blizzard’s service with Destiny 2 in 2017. It was the first time a non-Blizzard game was available in Battle.net.
No announcements have been made yet. Stay tuned.
