If they end up with anything like this, it would be an improvement. They're really going to need to find a way to move people across these long distances more quickly as these concourses expand. Even a bus system like PHL has would be better than nothing. I wouldn't expect to see any kind of train/people mover system.

At any rate, this is years and years down the road. So, the suck is going to be with us for a while yet.
