Since this official Microsoft-provided art has now been retracted (from Games Press), you're either looking at an elaborate labeling error or an accidental announcement of Fable 3 heading to PC. We'll do our best to be royal pains and keep bugging Microsoft for a proper answer. At the time of writing, neither Microsoft US nor Microsoft UK had responded to our calls.
Update: A Microsoft representative told us, "We have not made any official announcements beyond 'Fable III' for Xbox 360 at this time," and offered to forward additional information "as it becomes available."
