I'd say it's probably on hold at the moment until they see theme park and studio operations back to a near normal level.
Not really. Work on the BoH Campus has stalled, likely due to COVID. The last update was from the end of May. We were hoping that Peacock Live, scheduled for the end of March, would give us some more information, but that was cancelled.
Going to take a guess that the BoH campus will eventually get back on, as it was being worked on prior to the closure of the park's and the studio.
Plus from what it sounds, the studio campus is open again--albeit with different production procedures and guidelines.
