@subtledoctor I recommend checking out the in-app purchases screen. The reduced price for the iOS version is because some of the extra goodies (portrait pack, sound sets, Neera, Dorn) are split off as premium content.
When you first launch the game on your iPad, tap the big artwork pieces to the right of the buttons, and that will bring you to a screen that displays full descriptions for each content pack.

Though, the new voices aren't in default BG2 which makes me sad QQ
Hopefully with the release of SoD and the super patch it will make the soundsets be in both games.
