Barry Braverman's quote in this Disney press release seems to confirm this is an identical copy of the DCA film. I expect that they will even keep the finale' scene where you sweep over Disneyland at Christmas, flying past the Matterhorn and Small World Holiday. Perhaps later Epcot will get a new film that isn't a big commercial for the State of California Chamber of Commerce?
The Braverman quote from the Disney Press Release:
"The genesis of the idea goes back to the simple observation that one of the things that is most impressive about California is that it's just drop-dead beautiful," said Barry Braverman of Walt Disney Imagineering. "We have the ocean, we have Big Sur and we have the mountains and desert -- an unbelievable variety of terrain and spectacular topography. Clearly we wanted to use film to capture the beauty of all that but how do you do it in a way that's never been done before?"
