I got to see the first showing today. No more water effects on the audience at all (even the jet skies now execute turns that don't splash into the audience). The pre-show is now just getting the audience to stomp their feet (probably the best they can do without being able to splash people any more). They do wear a sort of neckerchief mask, which they do pull down while performing on the water.
Also, because they spread out the audience so much, it doesn't take much before the stadium fills up...so if you want to see this show, you really have to be there a minimum 30 minutes before showtime. They escort you to a seat, and you leave in groups as if being dismissed from a classroom one row at a time.
Show was not all that different, but the pacing felt a bit off to me. The plane didn't fly over, although all the other effects went off for it. I figure they're still getting their footing back.
