There is no official date yet, so far Ubisoft had only officially announced the development of Assassin's Creed Mirage , but there are some leaks that ensure that the game had been delayed internally. That it has been delayed internally means that the launch date was scheduled for August 2023, but with this delay it would be released in October.
The information has been shared by the well-known and always well-informed, Tom Henderson . He has been the one who has shared the information that the launch of the new game in the saga was scheduled internally for August 2023, but that it will arrive about 3 months later. Of course, as you know, Ubisoft hasn't given an official release date to the public, so while Henderson doesn't release information lightly, we should take it with a grain of salt.
Assassin's Creed Mirage would arrive in October 2023
It seems like AC Mirage has been internally delayed from August to October. Nexus, AC's VR offering has also been delayed a couple of months.
