It's obviously Flying. It's way of flight will be like Tropius's, probably. It's not hard to imagine that it will rotate the "bows" at the back of it's head.
It would be nice if that rumor's true, but I don't quite understand the purpose of talking to your pokemon...Unless, it's like you have many several options, but it will still never give the atmosphere of anime.
