I've never posted here before, but I thought I'd de-lurk long enough to pass along some information I found (some of which is already known):
I went to the Hippodrome Sunday 3/29 to watch CATS, and while I was there I talked to someone who worked there (I don't know exactly what her position was, but she wasn't an usher, as she was carrying a walkie-talkie, was wearing business-casual clothes, and had a badge hanging around her neck).
Anyway, when asked when the line-up for next season's shows was going to be announced, she said April 23.
I then asked if she had any idea or guesses as to what some of those shows might be. She said the only thing official she could tell me was that which has already been posted: Young Frankenstein, In The Heights, and The Phantom Of The Opera as a special. Were she to tell me anything else, she said, she'd have to kill me.
Knowing this, I decided to mention the fact that I'd read rumors/speculation online "somewhere"

that there was a possibility of Wicked coming back. She said that wasn't a "reliable" rumor and that it likely wasn't going to happen.
Yes, I know she could have been saying that just because she wasn't able to confirm anything if it was true, but I just thought I'd share it anyway to let you all make of it what you will.
I shall now retreat back to my solitude of message-board-lurkdom.
Thanks!
