That's funny because I was talking to someone in another thread (I think one of the "how do they do that?" ones) and they swore that MK HAS been doing it daily already (this was several weeks ago). This was from me talking about how when I worked as an Ent Tech, I had one of the guys show me the old console where the tech would release the "brake" on the sword when given the signal and how they had cut the wires so no one could come up there and free it now. They told me they hadn't heard anything about a room with a control thing in it (but as I stated, it's been 4 years since I worked there, so they could've fixed it easily), but now I'm reading it "might be coming back." Guess I wasn't going as crazy as I thought.
I can tell you that the sword and the stone magical moment happens multiple times daily. The Fantasyland Woodwind Society is out daily and they could of just been around the sword and the stone when the magical moment was being performed. One of my friends said today that she crowned a little boy after he pulled the sword out of the stone so maybe there might be more to it. If I find anything out about this I will post it!
