I don’t know what the eponymous creed in Assassin’s Creed is, but if I had to take a guess, I’d say it was something along the lines of, “Bring out an Assassin’s Creed game every year; preferably with a subtitle instead of a number after it, in order to curb expectations as to what a sequel should entail. Also, stab people in the throat if they don’t agree with you.”
It seems Ubisoft have taken at least the first part to heart and so unveiled Assassin’s Creed: Revelations. The cryptic teaser trailer merely contains the the name of the first game’s protagonist written in Arabic, implying a return to his era, just as Assassin’s Creed: Brotherhood continued the story of Ezio.
Whether this also implies a return to the Holy Land is a different matter, but I for one won’t be interested unless it turns out he discovered a way to time-travel to Revolutionary France and become the Scarlet Pimpernel. (Or one of The Three Musketeers, I’m not fussy.) Adam
