Mike’s post wasn’t the origin of the rumor, at least from my perspective. I had heard the rumor prior to realizing A&D leadership had attended the event. Mike’s post was a period on a somewhat rambling sentence, as it were.
I haven’t heard anything since I posted my clue, which is always an unnerving sign. The quirk of such early rumors is sometimes I’ll catch wind of ideas that don’t actually progress very far (like Game of Thrones, which from my understanding was brainstormed by Universal but never pursued). Unfortunately, I won’t actually know what became “real” until later.
I still expect a house in 23A though.
