That's the Hurricane Central wall, which is the only key wall in 1A. For some reason, they never bothered to install proper lighting for that key wall, so we're stuck with it until the HD relaunch. The old key walls were in 1B, so they can't use them anymore. It looks like Vivian might be using the key wall in the A&B/WV studio judging by the tight camera angle being used. Either that, or they might have left one key wall in 1B running; Viv is using a wired SkyTracker clicker after all, and I don't think they have those in the A&B studio. If they were in the A&B studio, that would be an annoying trip for the OCMs to have to use a studio so far away from the one they're in. I wonder if they would play Rock, Paper, Scissors to determine who has to make the arduous trek back and forth between studios for the entire show.
One cool thing about the Hurricane Central wall is that the OCM there can chat with Dr. Forbes since it's so close to the Expert Desk. Jeff did just that earlier during the Weekly Planner.
