Ubisoft: There is an "overall arc" to the Assassin's Creed series
Arc can be expanded “depending on what fans want,” but there “is an end”.
Given that it has almost the entirety of human history to play with, and that it’s currently releasing games at the breakneck rate of one per year, you’d be forgiven for thinking that the Assassin’s Creed franchise will go on making games until the end of time.
