I question the problem that lies in having separate megaservers, if you're playing PC you can't play on the same servers as those on PS4 or Xbone, why I don't know. I used to play Final Fantasy XI back in 2003-2004 on the PC and a good portion of the population were on PC and on Playstation 2 on the same servers without any problems. I see a greater split once the console versions release and players choose to migrate/transfer away from the PC onto a Console; this deepens a wedge in the PC community further driving more players away as the numbers get smaller and fewer people to interact in game.
