According to this article, concessions will move from interior to exterior walls, and that will allow expansion of concourses into those "former" concession areas. Not sure how that will work -- need to look around when I'm next in Hilton. Also, the new concessions will "be equipped to serve greater variety of food." I don't care as much about the variety expanding, as I do have truly hot hot chocolate and coffee, and that the creamers don't have chunks in them anymore.
