A new ride? Yes. A new 3-D movie? Not yet. Essentially Phase II or III (I'm waiting on a more definite answer on that question) of the Imagination refurbishment for Version 4.
From what I'm allowed to tell:
Rivers of Light at Animal Kingdom
- A brand new parade set to be shown at night (much like Spectromagic does at Magic Kingdom).
- Using bright lights and colorful music, will essentially "flow" through Animal Kingdom's dark paths like "Rivers of Light"
- Will be the last piece necessary for the extension of hours for Animal Kingdom (most likely to 8:00 p.m.)
- Will be announced in 2008 (I have an approximate date, but I can't say it until our Wild Decade event has been given clearance by the company) and will start lighting up Animal Kingdom in 2009.
