Waiiiit a second!?

A long time ago, in game years, an MMO came to the PS2, FFXI. At the time, the graphics were decent and gave non-pc users the ability to play FFXI. However, several years later SE wanted to upgrade to the PS3...

" 'Initially we were in talks with a representative from Sony [to achieve this], but it appears that that person quit,' said FFXI producer Hiromichi Tanaka, inducing laughter from the rest of the team. Tanaka also explained why it's a little more complicated to make the PS2 version work than, say, simply releasing some sort of patch or update for the PS3." - 1up.com

(I remember an episode of either LBR, Limit Break Radio, or Aetheryte Radio talking about this also. Love you guys btw!)

Anyway, that was that.

So, I understand that the graphics look great now. I also know that the xbox720 is due out in the next few years.
My question of speculation is what happens in another six years or so? Yes, first we have to get there, lewl, however, presuming that FFXIV will be around and doing decent after all the remodeling now and in the future, what happens when it needs a graphics upgrade? An MMO called Mortal online had a huge graphics overhaul and looks great in comparison to what it was and for who their dev team is. Aion also had a graphics upgrade patch of some sort.

Is FFXIV, like its predecessor, going to be tied to it's current consoles and how much can it be upgraded on these systems after expansions, updates, and players going to the newer gen consoles?

(Yes, space shouldn't be an issue)
