Divinity 2 has it...
but not to the standards Skyrim could have it...
Divinity 2 was a good game. Even though it was very linerar and short. I still liked it. The abilty to jump off a cliff and morph into a dragon was just so epic. The combat was better then any Elder Scrolls games. I do hope they make combat better in Skyrim. The combat was so bad in morrowind and oblivion. At less bows worked in oblivion.
The are making the game actully playable in 3rd person. So changing into a dragon is a posiblity. Unless it goes against the books. Never read the books but would be nice to see something specail with our character as they are the last dragonborn. I want to see some specail dragon born abilities.
