FFI, FFII, FFIII and FFIV are seeing this treatment, FFV and FFVI was remade on the PS1/GBA, it's very likely that they will do the same for FFV and FFVI on the 3DS or PSP.
What I don't understand is that why would it take so long? what is their reasoning? I may be missing why it would take 40 years to remake a game, did I miss something?
IMO though if they did remake the game I would want them to make it the very best they can make it, like for instance if they want to "polish every stone 3-4 times" I say let them, its been so long after all I don't know about the rest of you guys but I'm happy to continue playing my original version untill they get every last detail perfect.
