Microsoft has promised to keep Call of Duty available on PlayStation for several more years after the current marketing agreement between Sony and Activision expired, assuming the acquisition of Activision Blizzard goes ahead.
According to a report by The Verge, Microsoft gaming head Phil Spencer promised to guarantee Call of Duty on PlayStation, with feature and content parity, for at least several more years beyond the current Sony agreement.
Spencer has already made several public remarks that have the same general effect, noting the relevance of the PlayStation community to Call of Duty, and comparing the game to Minecraft, which Microsoft has maintained since its acquisition of Mojang in 2014. But this is the first such statement to guarantee the availability of Call of Duty on PlayStation beyond the terms of existing agreements, although vaguely.
Microsoft is adamant not to portray its acquisition of Activision Blizzard as anti-competitive, as it is subjected to intense scrutiny from governments around the world. So this is one leak Spencer and his team will have been quite happy to confirm.
Spencer confirmed that Call of Duty games will be coming to Xbox subscription service, Game Pass, last week, although it's unlikely that they will be unavailable on competing systems like PlayStation Plus. This appears to be a quite differentiator for Microsoft as it strives to broaden the notion of game platforms beyond the home console.
