We are already learning new things about the Saturn system. We will fly by Phoebe on June 11th and that's a very interesting moon. We presume that it's a captured object. We don't know what population it represents. Is it an asteroid? Is it a Kuiper Belt Object?
Those are the kinds of things that we have theories about, but we really don't have data.
So we have more than enough to keep the E ring from disappearing.
We will get stereo images within a month.
It's going to be the most exotic place we've ever seen. We've never landed on the surface of an icy satellite. We know from our pictures that there are very different kinds of geological processes.
