My entire point here is that we don't know what is going to happen. The claim that "3K is history for WNBC" seems premature as the only thing we know is that the two stations are moving into a shared workspace. Shared workspaces does not equal new studios. Like I said, I hope WNBC does get a new set but there's no evidence at the moment to support that. Only speculation.
I haven't forgotten that 30 Rock used to be filled with radio studios. But all of the radio studios that were capable of being transformed into television studios were converted over half a century ago. As for Studio 1A, it used to be a bank and the ceiling in that space, as is true for most ground floor retail space, is a story and half. In fact, the area over homebase didn't have a ceiling above it at all. You could look down from what is now the SPA into Studio 1A.
But my aside about construction clearly became a distraction from the fact that neither B&C or NewscastStudio made any mention of WNBC getting a new studio.
