FFXI is dying, there is nothing more to it. Starting over is a pain in the *** for fresh players, and like previous posters mentioned; The game is in an end-game stage.
I have converted to WoW recently, simply because i was tired of going to the three same places everytime I wanted to get a level to 30 (Dunes, Qufim, Kazham). Tired of hacking away at the same mobs all the time, being in a party where no one says anything, and if you do you dont get an answer, wich pretty much makes you wanna shut up for the rest of the session.
Im guessing the lvl70-75 players still enjoy the end-game stuff, and thus they will probably make the life of FFXI a bit longer. However, FFXI will not grow in population. This game is anything but new-user-friendly considering todays standards in MMOs. A new PS3 launch will probably be as clumsy as the previous XBOX360 release.
I loved the game back in the good old days, where mostly any item was up for sale on the AH, and you could find out things together with your exp party. Where everybody was interested in doing the best SC.
And I will be the first one in line if SE ever decides to release another, more user-friendly MMO.
