From the Oriental Land Company's press release:
The revamped version of the attraction will have new lighting effects and other special show effects. In addition, a specially written musical sound track will be heard throughout the attraction for the first time in any Jungle Cruise. Also, an after-dark only “night cruise” will provide a unique take on the jungle adventure.The new Jungle Cruise will offer Guests an adventure that is even more thrilling than before. From on board the attraction’s boats, Guests will explore jungle landscapes full of wild animals with the help of their daring and comical skipper who guides them through the beauty and dangers of this exotic world. The adventure includes a startling encounter with one of the animal spirit guardians in the ruins of a lost jungle temple.
When TDL completes the Jungle Cruise makeover in 2014, it may end up eclipsing DLR's attraction. Should Disney plan the same thing for Anaheim?
