There will be some happy people, and some disappointed people. Both systems have plenty to offer, so no one should be too upset.

Although I was a "Titan Now" kind of person, my first reaction is more of excitement than disappointment. Two orbiters? Not too shabby. It will be great to see the Jupiter system get the complete Cassini treatment... times two!

Just curious. Does anyone think that there may be plume activity on Europa similar to that on Enceladus?

Plume activity on Europa can't be ruled out, though it's perhaps not very likely. Europan plumes would be much smaller than those on Enceladus (more like Prometheus-sized), due to the higher gravity, and might have been missed by Galileo, which of course had very limited ability to do extensive monitoring. And remember that on average, Europa's surface is much younger than that of Enceladus...
