I'm sure NBC isn't going to do a Disney show, because of the Disney/ABC partnership (or rather ownership). As much as one of their recent musicals like Poppins or Beauty and the Beast would fit the bill nicely, it won't happen.
Neither will The Wizard of Oz, unless it is a joint venture with Warner Bros. and Ted Turner, who own the rights to the MGM film (and script and music).
I hope they do THE WIZ. That could work well with the right concept and cast. I think enough people know the songs, and if you star-cast the leads ... it could draw big numbers. Unless the network(s) are afraid of a $9 million all-black musical. I hate to even say that in 2013, but viewer demographics definitely play into decisions like that.
