Where are Eorzeans heading to in the distant future?

one thing that i think would be a great addition is Free Company vs FC , 8 players from FC1 vs 8 players from FC2, instead of the norm 1 vs 1, though it should be just an option, so thats something..

I think for the larger scale PvP battles it's been mentioned that all three GCs will fight each other, but I haven't heard anything about FC fights. It's been said that FCs DO pledge themselves to a single GC (which is kinda odd considering you have people from other GCs in your FC) so maybe they'll just keep the fighting between GCs themselves. They might introduce something later on for fights between FCs, like Ballista or Brenner, if the demand is popular enough.
