What happened with Odin?

The end of Thor: The Dark World saw Loki standing on the throne, thus implying that Odin has left the MCU. Furthermore, director Alan Taylor said that the All-Father is certainly dead. But there is a problem in here.
Even in this shared continuity, Odin has been depicted as one of the most powerful beings in the Universe, way above even Thor. If he is indeed that powerful, can Marvel settle for an off-screen death for him? We guess not – and even if the director said something, we can bet that we haven’t heard the last of Anthony Hopkins’ character.
So the biggest possibility would be that Odin has been imprisoned by Loki (and some other powerful ally), or even banished to Earth (as was Thor in his first solo flick). If this is the case, it would be an interesting twist which might help develop the character – from a position of ultimate power, Odin would have to deal with the problems of everyday life and try to escape.
Of course, this would also bring another fake death – which, as said before, is not a welcomed event. So what will it be? Is Odin dead? Or will he make another appearance in Thor: Ragnarok?
