So if nobody has already patented this, and the patent office doesn't decide this is so obvious as to be unpatentable, the new law might actually help.
BTW, I'd expect to see a lot of patent filings over the next month or so, as there may be many things that other have created that they didn't patent, and that patent-jumpers can now claim.
That is definitely Shanghai Pirates. The lake part will be a show similar to the one in DHS, and the boats (or at least the upper part of the boats) will turn to the center of the stage while continue to navigate sideways, and the guide channel part will be similar to the traditional pirates attraction.
A chained boat is the worst way to enjoy a boat ride. What would have gotten me excited is a kuka robotic arm that holds a boat and takes the boat on a journey with simulated jumps and spins. I give you this idea for free.
