The official Ace Combat site has been updated with a new title. All we have is the teaser above. What could it mean? According to one Facebook comment the Kottos is a reference to 6.
A line from AC6, Kottos was one of the Electronic Support ships with the Aigaion.
Will the new Ace Combat continue using its DFM "COD in the air" formula? Will we ever dance with the angels again? Let's wait and see.
