Kingdom Hearts titles are on the way, as Square Enix announced brand new titles in development for the DS, PSP, and mobile phones at the 2007 Tokyo Game Show.
1UP reports that these will be three entirely different titles, although all three will share the theme of "time." Kingdom Hearts: Birth By Sleep will be headed for the PlayStation Portable as a single-player action-RPG romp in the same vein as its PS2 brethren. Kingdom Hearts: 358/2 Days for the Nintendo DS is a full-3D game starring Roxas from KHII, and featuring simultaneous four-way multiplayer.
The final title, Kingdom Hearts: Coded, is being developed for mobile phones, and features the original Kingdom Hearts cast in a story that appears to take place in between the first and second PS2 games.
