well im almost certain there will be some dragon shapeshifting element to the game being a dragon born character, as i read in an article with todd howard were he hinted at the shapeshifting goal they were going for and used examples like the bloodmoon expansion from morrowind but he wouldn't confirm or deny shapeshifting into dragons,werewolves,or vampires, he talked about horses and whether they would make an appearance, he said he didn't want to bring the horses of oblivion back, he wanted to bring a more realistic and satisfying horse experience to skyrim and if they can't then he'd rather not have them at all, it would kill the flow of the game in his opinion.
If you're talking about the Podcast in Game Informer, he didn't say anything at all of Shapeshifting into a dragon.
When he was talking about bringing shapeshifting back (Maybe, not confirmed) That it will most likely be werewolves again, or werebeasts. Most likely not dragons, for they are the "bad guys."
