All Disney releases are coming out in the combo packs that have a Blu Ray, DVD and a digital copy for your iphone, ipod or digital device. Any subsequent release of the same movie will be out on DVD only a few months later.
Only a year ago, I finally got all Disney/Pixar movies on DVD and now we're in the process of converting them all to Blu Ray and giving all the DVD movies to my partners nieces and nephew. We're trying to desperately convert the children to become huge Disneydorks like we are.
I do have to say that the Blu Ray versions we've bought, especially the latest Sleeping Beauty, are absolutely amazing. I've never seen SB so colorful, bright and clear in my entire life. I'm so anxious to see Snow White now that's it's been cleaned and restored. Blu Ray players have drastically come down in price and you can play your dvd's on them and they'll even look better then before.
