So thrilled it's happening!
I honestly imagine them to treat the movie as a old golden age movie musical. Snow White was the first Disney animated movie, so I think (or at least hope) they will treat this with great respect and care. Including the music.
I just hope they don't make Snow overly feminist. Her purity and kindness is why I love her so much. You can make her modern, but don't overdo it.
I am also worried and curious about the casting. Snow's voice is so distinctive and unique, I would hate if they hire a non-singer or pop star for Snow. Above all, please hire little people (is that the right saying?) for the Dwarves, and not do CGI and motion capture for them.

If Mirror Mirror did it, so can Disney!
