While NIS America is plugging away at Cave Story 3D, their parent company in Japan is developing Bikkuriman Kanjyuku Haoh, a game based on those stickers you get with Lotte's chocolate wafers. The Nintendo 3DS game is a tabletop style game where you combine kanji on the stickers to make words.
Bikkuriman Kanjyuku Haoh is slated for a summer release in Japan. A North American release has not been announced and given the kanji combining gameplay system I'd say it's unlikely.
In addition to Bikkuriman characters, a bunch of Disgaea characters are in the game too. Prinny, Flonne, and even Disgaea 4 star Valbatoze are confirmed for the Nintendo 3DS title.
