Xbox's Mystery Sequel: A 10-Year Development Journey.

Xbox is reportedly working on a mystery sequel that could take up to a decade to develop, according to court documents related to an ongoing legal challenge against Microsoft's acquisition of Activision Blizzard. It is unclear if the game is a completely new title or an already announced game like The Elder Scrolls 6, which was revealed in 2018 and is still in the design phase. The plaintiffs in the case have filed an amended lawsuit containing redacted information from Microsoft, including a strategy memo, and new information from the deal’s chief opponent, Sony Interactive Entertainment.
