Baldur's Gate: Enhanced Edition announced for iPad:

Details are scant, except that it will have all the content of the PC version and it's due for release this summer. IGN has impressions:

Judging by the photos in that first link, it seems like the biggest problem is that the BG UI doesn't scale well to a 2056 x 1536 display.
While we wait, if you're looking for a kickass WRPG for your iPad, I strongly recommend Avadon: The Black Fortress. It doesn't have voice work or much high-quality artwork, but it does have a kickass story, an elegant turn-based tactical combat system, skill trees, surprisingly good inventory management, and (holy crap!) difficult moral choices with actual consequences:
