Just announced during a special livestream for the game. They announced that the 3DS version would get 2 costumes: Link and Zelda from Hyrule Warriors.Here's a pic:There's also some Toukiden Kiwami costumes to unlock if you got save data for that game (PS Vita only, obviously), and some Samurai Warriors 4 DLC you can transfer to this game (again, PS Vita only; and not all DLC). Oh, and demo version is coming out tomorrow, for both platforms.Demo can be played for 8 minutes (Battle of Nagara-gawa), and you get a special achievement when you play the full game.
