No idea if this is a port (lol) or a new game, but in any case it's coming out sometime in March by AQ Interactive.

Feelplus is listed as the developer (no mention of Artoon), and no specific staff members are mentioned except Sakaguchi as producer, but the press release does confirm it will be in the same universe as the 360 version, so it won't be based on the horrible anime.
Note that both this and Away will be 5,980 yen, so either they're ASH-sized carts or Mistwalker has deemed that their titles can command a premium these days.
