Hey gang, this ride IS NOT GOING TO BE AS BIG AS IT LOOKS! The building may be just short of 200 feet, but the ride itself is not going to be any bigger than Rock n Rollercoaster.
What follows is the listing from Roller Coaster Database:

Amusement Park: Walt Disney World - Animal Kingdom
Type: Steel - Sit Down
Status: Under Construction opening 2006
Make / Model: Vekoma / Custom Other
Cost: $100,000,000 USD

Height: 112'

Inversions: 0
Speed: 50 mph

Trains: Riders must be 42" or taller to ride.

History:

This will become the largest ride in Walt Disney World at a cost of $100 million (USD).

The ride will travel both forwards and backwards.

The height of the attraction is said to be nearly 200 feet. This is probably referring to the height of the mountain and not the height of the track contained within.

The Expedition Everest will be the first ride to use Vekoma's newest track system. Rather than the rails be on the inside of the ties, they will be on the outside. To date Vekoma has only used this system on their smaller roller coasters. This will be the first large scale installation of such a system.

So, in terms you'll all understand, The Yeti isn't the biggest, baddest monster in Orlando. That honor goes to Kraken at Sea World, followed by the Dueling Dragons(reportedly a ride passed on by Disney).
