FFXIV is being re-made to get the players currently playing WOW and other mmos or not playing mmos at all. They aim at reaching a wider audiance and hope of eventually getting a player base similar to what WOW has. SE doesn't care about making this game into a niche like FFXI was they want to get the casuals, hardcore and as many different type of players as possible.

So to those that keep asking for a FFXI remake or to make FFXIV batshit crazy hard like taking 18h to kill a NM(FFXI).. it won't happen.
