I kind of feel (without having set foot in one) that having less stuff on the shelves would take something away from the experience. If I just wanted to shop through a terminal I'd rather do it from the comfort of my own home. Part of the magic of the shop was the themeing and discovering things I didn't even know I wanted.
I'm going to Hong Kong in January but the only one I know of there is in the airport. Is it likely to get the change as well or is it run by someone else?
