That dock is too thick to be only a charging station/TV connection, I'm betting on additional hardware sitting inside it too. Another rumor I read somewhere else justified the extra thickness of the dock due housing a hard drive for additional storage (but then, how would you transition seamlessly from the TV to portable mode, like in the trailer?)
