It's not likely to happen.

Is there talk of a PS3 version of Final Fantasy XI in the works?
If we were to start developing a PS3 version now, it would likely take about 5 years to complete. By then PS4 would be out and there would be talk of a PS5 before we could release it. It would be too much work, so we have no plans to create such a version. The PS3 can play the PS2 version, though.
They estimated 5 years, back in 2007 when they had full development staff on the game, to port it to a new platform. It's such an old game, a new release isn't likely to attract enough new players. Nintendo also does not seem to be receptive to cross platform play with competitors, and trying to get new players going in a game with people with a 15 year head start is tough.
