Hopefully once the big projects are out of the way, or once they start working on the Kidzone redo, they will look at this ride, and try to fix the bugs. I think this ride can be improved, and what they can do is work closely with Maurer Söhne, and create brand new cars. They can start from scratch if they want to. Then, they can rebuild the moving walkway to speed up the load. They can reroute some electrical cords if they need to.
This is most likely blue sky, and just some crazy kid from Jersey's fantasy since I love this ride. They will wait to see how Potter and TF affects the rush for this ride since this is a popular ride, and a ride that everyone sees when they enter the park. Not to mention that this ride often gets a wait time similar to the new Despicable Me attraction. So this might not happen for a couple of years, but don't think Universal Creative doesn't care about Rock It. I guarantee everyone that they have an eye on this ride. They know they can do better. You'll see.
