I saw this on Eurobricks, apparently its an advert included with the new Hobbit Lego sets for this year. Nice to see it confirmed even though it's still over a year away.
The game will only cover the first two films which is just stupid to me, why not wait till the end of the year and they can do There and Back Again as well.
Though I suppose this way they can sell There and Back Again as DLC or release an extended edition later in the year or in 2015.
