I was at the store today and finally caved. I was going to pass on this but I saw the unboxing video and really like the pages of extra content in the Digibook. I like Digibooks with movie making info and stills as opposed to the ones with a kid's storybook in them.
There is also an extra special features disc.
I purchased it, but yes there are two editions.
One edition is just the digibook + digital copy.
Another edition is the first edition + additional J-card and ticket offer. Both editions are available in-store but you have to check that it has the sticker if you want the movie money. The sticker has the code.
