There's been talk that Hexe, the code name for the next Assassin's Creed game, might take place during that period, as it involves the rise of the great witchcraft hysteria that plagued both Europe and North America during the 17th and early 18th centuries.
However, be aware that this is just speculation at this point, so feel free to take it with a grain of salt (as in, it may be subject to change).
Here's hoping that a bugfix patch is also implemented alongside the new DLC content. Getting fed up with not being able to safely make female superstars without the game just crashing seemingly on a whim.
