If you remember, Assassin’s Creed Rogue was announced back in 2014 for PS3, Xbox 360 and, later, for Windows PC.
Strange movement, since PS4 and Xbox One were a reality. In fact, the same day that AC Rogue was released for those past-gen system, AC Unity was released for PS4 and Xbox One. However, Ubisoft never spoke about a release of AC Rogue for current gen platforms.
