From the blog:Disney Parks Blog
"Our friends at Tokyo Disneyland just announced that a new version of Jungle Cruise – Jungle Cruise: Wildlife Expeditions – will debut at the park this fall.
The attraction has been popular with Tokyo Disneyland guests since the park opened in 1983. The new version will feature enhanced special effects and lighting, new original music, and a new “nighttime” version that will offer guests a thrilling new look at the jungle.
Jungle Cruise: Wildlife Expeditions will officially open at the park September 8, 2014."
This is pretty vague... I wonder if there will be more involved then they are letting on. I mean, if its just a small plus to the ride, they don't normally publicize them. They didn't with adding music to Space in Florida, and they didn't when they added new effects to Indy in California. So, I am thinking there will be more to come on this.
