Right. It's a Y2K thing.
Also, they're now working on Terminal E. What's Terminal E, you may ask? Well, imagine a mirror of Terminal D (née IAB) coming off of the wing of C where gate 48 is. That's pretty close to what it'll look like. There will also be a skybridge of sorts connecting D and E, between the east garage of C and the parking lot for D (hopefully that will become a parking garage). There will be a monorail stop in the middle of the skybridge.
