Though you're already familiar with Final Fantasy XII: Revenant Wings (slated for the DS), you may not have heard of the other two games revealed in the latest issue of Japan's Shonen Jump. The pages first mention Final Fantasy Tactics: The Lion War, a PSP remake of the original PSOne Tactics game. Some new cutscenes and a slight graphical upgrade are likely to be included, though we certainly wouldn't mind a better localization as well -- that's assuming the game makes it stateside. Secondly, there's (deep breath) Final Fantasy Tactics A2: The Sealed Black Book. According to the translation note on Jeux France, it hasn't yet been specified whether it'll wind up on the DS or, as the horrific machine translation puts it, the "Game Servant Boy Advance." The latter choice, of course, will result in the game working on both platforms. Snap to it, servant boy!
Another magazine, Gamelabo, reportedly mentions that Square Enix also has two more unannounced Xbox 360 games in the pipeline.
