You said early 2015. It's the middle of February now... Come on guys. I love games like this but I don't have an iPad
I'd be surprised if we ever see an iPhone version. The gameplay does not lend well to such a small screen, with card text being well below a readable level. They'll need to solve a lot of UX concerns before that happens and then, if it's not a straight port it now doubles their update work as they maintain separate builds.
