Yes, we are working on a Universal update. Yes, it is taking a long time. No, iPad users won’t have to pay for this separately. No, we don’t know when it will come out.
Here is a sneak preview of one of the dialogs. You can see that we’ve enlarged text and buttons (since you hold an iPad differently than an iPhone). And since there is room to fit all the advisors all the time, it’s easier to consult them. But it’s the same dialog as always — you won’t have a different play experience on iPad (although the larger screen does make some things easier, such as less need for scrolling text).
This is the only dialog that’s completely converted to the new look, so there is a lot more work to do. And we still don’t have all the new artwork. But there has been progress.
