I have to say, I'm a little upset that the 3DS will get characters not on the WiiU. It's a bit ridiculous when we pay a premium for content and then they give all that the $40 game and then some. You can't even buy a used copy of Hyrule Warriors for less than $50, then you have to spend over $20 to get all the DLC.
But... maybe it'll be worth picking up again. The game is quite incredible. Having it on a mobile platform would be awesome.
