Having the same collection of cards available for both your iPad and PC, as well as cross-platform play, would both be awesome features we’d love to have available. But it’s pretty technically complex, and we're not sure yet when it will be ready. Both the development team and our Battle.net team are looking into it now, and we'll let you guys know when we have an ETA for those features.
I had posted a couple things on Twitter that had made it sound pretty set-in-stone, but that's not the case right now, sorry about any confusion.
