It was announced this week that the Lion King will be ending its run at Mandalay Bay in late 2011.
This likely paves the way for the new Michael Jackson Cirque du Soleil show to take over the Lion King showroom in 2012. The Jackson show will be on the road touring in 2011 before settling into a permanent home in Las Vegas.
Mandalay Bay has always made the most sense as the home for this show. It is clearly the best MGM Resorts property currently without a Cirque show. The Michael Jackson show will also include a themed nightclub, which could presumably be located in the closed Rumjungle space.
