"There is an end" to the Assassin's Creed series, Ubisoft says

[JEMC]

I'm sure the interview was in French and they messed the translation .

I'm sure what the game director said was that they "had" an ending, but when the franchise became so big Guillemot told then to scrap that ending to keep making games. That's why he has a "rough idea" of how it will end (which means that he has no clue), and that they have to adjust it with every game they make.

The sad thing is that they could do it without killing the franchise, just ending the Desmond arc and start another.

*Spoiler ahead*

Desmond is there to stop the Templars from getting the fruits to control the people (because as seen on the first game that's what they want), and prevent a catastrophe like the one that happened in the past (as seen in 2 and Brotherhood).

The solution to that is easy, given that the Templars' plan is to get the fruits and put them in orbit with satellites to control people's minds (I think), Desmond and the rest of the Assassins "only" have to let them get the fruits, put them in orbit in sabotaged satellites that will be controlled by the assassins and that disposed in the correct places will prevent the catastrophe from happening, after which the damaged satellites will fall again on Earth. That way they can end Desmond's arc (even with Desmonds sacrificing himself for the greater good), and start a new arc set in the present as they try to recover again the fruits as well as keeping the Animus and the past arc settings to either train new recluits, find evidences of new artifacts/tech, etc.
