I think they eventually will do a 2.0 not anytime in the near future but if this game lasts for another 10 years there would be no reason not to at that point.

One of the main reasons the decided to do it for XIV is because they didnt want it to become a "lost" Final Fantasy and if they dont do something then it will happen to XI. The only other route i can see them taking is making an offline single player version of the game.
