Considering Menken was the one who blew the lid of Aladdin coming to broadway before Disney officially announced it, I wouldn't be suprised if Hercules is a lot farther a long then we think. On top of that, Hercules wouldn't open for at least another 2.5-3 years. It is likely a replacement for Aladdin, whose sales should decline once Frozen opens next year, like Aladdin did to Newsies, and Newsies did to Mary Poppins.
