The technology that is being used for the water coaster has been around for a long time. I believe Wildebeest at Splashin Safari Holiday World was the first to use this tech in 2010. The load station will most likely be a conveyor belt. It will be interesting to see if it will be continuously moving or not. Most of these LIM water coasters are continuously moving but this is the first LIM one that launches directly into the ride instead of going up a conveyor lift.
Also, Crush'n Gusher is no where near the first water coaster. The first water coaster was built at Schliterbahn New Braunfuls in the mid 90's (1994 I believe). Hard to believe the tech has been around for 20+ years! I love the original Dragon Blaster water coaster. It starts low and slowly goes higher and higher with the water jets culminating in the largest drop from the tallest height to end the ride. Such a great ride.
Volcano Bay's water coaster seems to have a great mix of hills and turns with a couple of potentially good 'air time' bunny hop type hills.
