Washington, DC's WJLA (ABC 7) turns on HD newscasts

It's time to celebrate, DC, as you finally have more than one option to turn to when scouting HD news. For some four years, WUSA (CBS 9) has been the lone high-def news station in the immediate region, but at long last WJLA (ABC 7) has stepped in to give it some much needed competition. Reportedly, the station aired its first HD newscast during the noon hour on December 8th, with the next episodes to hit at 5:00PM and 6:00PM for those scooting out of work. So, which network has next?
