I have no idea of what it could be, but I could probably say it's safe to say that they won't be doing another futurisitic one in a while. XV could be on a par with VII or VIII's world. FF's been here for a while now and I've always wondered why they haven't had a FF with a Moogle or chocobo in the party?

I would also like to see some more of those characters that represent unusual classes, like Alchemists, Beastmasters, Dancers, Gamblers, etc.
