I think Wicked is still really hard every day, with several hundred people entering the in person lottery for the 25 or something tickets.
I think BoM is still really hard as well.
Neverland had a very long rush line over the Holidays, I assume is will be similar in the summer although I'm not sure how much of a draw Matt Morrison was.
SoR has long rush lines on the weekend, from what I heard but not sure how that will develop into the summer with more new shows opening...
Disaster is easy so far but it's still in previews. It might get harder with good reviews and depending on how the Tonys look at it. There are some great performances in the show, but I could see them snubbing it entirely. It could go either way, really, so check back in 2 months when the nominations are announced.
There are typically topics for rush lottery reports for every show on this forum, so if you just check back occasionally and search for those topics, that will probably be the easiest way to get a feel what the situation is with the news shows. Nobody's really talking about Wicked and BoM as they continue to sell out and it's hard to win those lotteries.
