I wouldn't call these spoilers since they are more so an easter egg but... Ubisoft's new Far Cry 3 insinuates that it takes place in the AC universe. I am not suggesting a crossover as many of the characters are annoying douchebros but perhaps more something along the line of a similar setting AU.

You know, the whole gang must fight to survive on a deadly island. Pirates, guns, kidnapping, tigers, craziness, action, drama, romance, etc.
