Yep, I've been waiting for it too but haven't heard a thing. Hasn't got great reviews but I just quite fancied it.
I got an Android tablet so I could play it (I'm not really into playing on my desktop)..I haven't in awhile so I should revisit it.
I'm sorry but you are talking about this game? http://toucharcade.com/2014/04/07/mojangs-card-battler-scrolls-is-coming-to-ipad/
