One of the AC: Revelations trailers goes like this:
- I have lived my life to the best of my ability -- Shows Ezio (walking)
- But I have not been able to escape fate -- Shows him sailing (to the Ottoman Empire)
- anger -- Shows him fighting and killing
- or pain -- Shows him being captured
- Bring me the answers -- Shows him fighting (for the answers)
- and the road that leads to truth -- Shows him looking at Altaïr.
- Reveal to me once and for all how all of this will end
Shows the Hidden Blade breaking.
That means, all of this will end with breaking of the Hidden Blade; or defeat of the Assassins.
