When's the release date?
Hopefully, the sequel is not just a Kinect title, as that would very irritating!
I enjoyed Fable II and Fable III, both for different reasons, but both had aspects removed or replaced, for instance the way experience was received and contributed to the level of your character.
Fable II had a better storyline in my opinion, but Fable III had the greater game play and sub-quests. From the article, Fable: The Journey seems to need to be developed much more than it has already been.
