one of our local McDonalds ripped out their outdoor play structure about a year or so ago and instead installed one of these kiosks. it is a 3 sided unit, it has a ps2, gamecube and xbox in it, all at different heights. (gamecube is lowest to the ground, then ps2, then xbox.) there is also a small touch screen game mounted on the wall next to it with a little bench. we were in there not that long ago and most of the controllers were broken. but i had a proud moment anyway when my 2 year old son walked over to it and said "daddy...xbox" and he was even pointing to the xbox controller.
i wouldnt be suprised if you see more of these poping up, especially since you can get gamecubes for next to nothing at this point
