The latest issue of Famitsu holds some new details about one of the new DS RPGs from Square-Enix, Final Fantasy XII: Revenant Wings.
The game mainly focuses on Vaan and Penelo, who are 18 and 17, respectively. The battle system for the game will be controlled by the DS's stlyus, as the game is a strategy game or sorts. There's no real timeline for the game, the story just mainly focuses on the fact that Vaan and Penelo being air pirates. The game will end up exploring the parts of the relationship between the two characters that the original Final Fantasy XII game could not, and Penelo's dancing ability will apparently play a much larger role in this game.
So far, no US or Japanese release date has been announced. Updates will be made when available.
