What really puts me off is we know that this films has Disney's first use of CAPS for the wedding scene.
This means that there is footage in the film that is available purely digital and can be used as a reference for the rest of the film. Every indication is that they aren't doing that though. This is the third or fourth color scheme for the film.
So far, I honestly don't get everyone's excitement. From what I've seen/heard so far it looks like Diamond-Edition-Business-as-usual.
