Note there will be TWO Assassin's Creed games this year, one for current and one for old gen
More screenshots in the link below.
These screenshots, sent to me by a source who requested anonymity, show Unity's new assassin roaming around what appears to be Paris. You can see Notre Dame, the Seine River, and other Parisian landmarks, and the shots are very clearly from an early version of the game
What's more, this is just one of two major Assassin's Creed games that will be out later this year, according to a number of sources. Unity will be for the current-gen consoles—Xbox One and PS4—while a second game, possibly called or code-named Comet, will be released on Xbox 360 and PS3. Presumably one or both versions will also be on PC.
