W00t, was poking around a little and found that
http://science.ksc.nasa.gov/robotics/ will once again be serving our Championship needs. This time, it not only has Archimedes, Curie, Galileo, and Newton, but it also has the Lego League and Vex fields as well.
So it seems that we won't be stuck with the NASA-TV webcast after all. /me breathes a sigh of relief.
