I've heard rumors about the Jacobs, but I can't find the link.
Personally, I think The Color Purple will close up shop in January. If the tony wins offered a big spike in grosses, we might be able to speak differently, but the show took a big hit when Hudson left, and if Erivo and Brooks don't make it to the end of the year, grosses could really go down. I hope it can stay longer since it's an amazing show (even without Erivo; I saw her understudy and she was still fantastic), but its grosses aren't stellar.
The Schoenfeld is pretty much the same theater, however; throw in a play for the fall and that could work too.
