Seems like Square-Enix can't keep anything a secret for their upcoming party! Rumor has it that Square-Enix will be giving Final Fantasy IV the 3d makeover treatment to appear on the DS. The team working on the game is the same team that handled the 3d remake of Final Fantasy III. Of course, Square-Enix has no comment, and most likely won't confirm anything until their party. I think it's a safe bet to take this one as truth. Thanks to Sicandblind for the heads up!
