Without going into the whole discussion at hand, I'm pretty sure a "2.0" version of FFXI isn't even close to being considered.
As it stands the whole genre MMORPG is a dying breed, most, if not all MMORPG are hemorrhaging subscribed players and there simply isn't enough fresh blood coming in to compensate for the loss of players.
The novelty of MMORPGs is gone, the novelty of FFXI is gone and a (one time) (fund raised) cash injection is not going to save it, maybe delay its inevitable demise for a few months, but save it? Nah.
It's been a good decade and some, and sure, if enough friends keep playing I might even add a couple more years to that if they keep the servers alive for that long, but all in all, good things come to an end at some point and all that remain are the memories of some of the best and worst years I've had in my life up to now.
