From everything I've understood--those stanchions that separate CityWalk, the security check stands that are currently there, and the park will be gone.
The only reason why they haven't tackled the security angle yet is because of how the hub is gonna be shaken up completely. I almost wonder how aspects like the tram that goes from the base of the mountain near the metro station, to where it goes now; will be altered as a result. I also wonder if this is why the globe hasn't been fixed--just because why do it now when you can do it while you redo that whole area.
