Off topic a little - is there any word...or rumor...of them filming other scenes for a totally new film? Here in Washington, D.C. this weekend I watched a commercial helicopter with a large film setup doing a pattern that started over the Potomac, flew over the Roosevelt Bridge past the Kennedy Center, Watergate, over Georgetown, then climb and hover over the city facing the National Mall (White House, Capital Building, Smithsonian Institution buildings, etc). It was, roughly, the same basic pattern that the Tahoe scene is from the current Soarin film.
It was a great weekend for it. Beautiful weather, cherry blossoms still out, whole city in bloom but not too dense like it is in the summer. The helicopter did the same pattern a number of times.
We watch helicopter filming take place all the time here in DC, and this rig was much larger than normal (which made me think iMax format).
