Square Enix has announced at the TGS that the Kingdom Hearts series will be heading to new systems next year including the Nintendo DS, PSP and on Mobiles. The DS version which is titled Kingdom Hearts: 358/2 Days stars Roxas from Kingdom Hearts II and is set to be a four player simultaneous game and will be in full 3D. The PSP gets a single player version in the vein of the other games and the mobile game is set between the first and second games. While it’s not a proper full Kingdom Hearts game fans should still be happy with either three versions..
