I, like you, have been checking out the pictures and fantasizing about the new ride. Honestly i think the subs were my favorite when I was a kid. I was thinking though there are a few things we aren't thinking of when we are envisioning this ride. Most of which boil down to the fact that this ride is not just diamramas anymore but projected computer anmimated scenes.
These scene houses are gonna be quite obvious as you come up to them unless they use the bubbles alot. And since they will need to let everyone see it, will the subs stop? How will they stop if they are propelled not on a mover-track?
Also - Nemo is a adolesent clown fish - in real life (from the subs perspective) he should be no bigger than an inch or two inches and marlin and dory a bit bigger. Its gonna be pretty hard to see what's going on isn't it?
The sound for each scene will have to come through the internal speakers of the sub. Now i can of course suspend disbelief to think that the fish can talk and that we can here them over the speakers but the scenes audio will have to sync up exactly with their mouths while we progress through the ride. This is alot more complicated if there boats aren't on a set track.
This ride has some major failure issues and will be burning some supplies as each projector will be on all day and night. Those bulbs have a limit of how many hours they can take. The bulbs will burn out alot and probably unexpectedly. How will the ride have a failsafe for that? The scenes will be pretty damn weird without the projections. Will a guy have to come out and change lightbulbs durning the show?
Anybody have anything else? This ride may be not as cool as we think and could be a technical disaster. I have all the faith in WDI (WED if you prefer) and I bet they can work them out but sometimes I just don't know if they thought of stuff like this.
