I see the FF AP being on all systems in different formats. FF1-3 collection on DS, FF4-6 collection on DS/Wii/PS2/PSP, FF7-9 collection on Wii/PS2/PS3/PSP/360.
Probably won't happen. It'll probably be something stupid like a Super Smash Brothers clone with FF characters from all 12 canon games, as well as Mystic Quest, Tactics(including Advance and the new DS one), and Crystal Chronicles.
