Codename Rapture Still Heavily In Development

FFU:

"In August 2005, it was announced that Square Enix were working on a new MMORPG, which they have entitled Rapture. This is just a codename for now though, as they haven’t really released anything else about the game.

Many fans presume that this secret (or not so secret) project is just a front for the sequel to Final Fantasy XI, which Yoichi Wada has confirmed is currently in development. At an investor conference on the 8th of March, Wada claimed that Square Enix are hard at work on the follow-up title to Final Fantasy XI and given that Rapture is the only known MMORPG that they’re currently working on, it’s not illogical to put two and two together in this instance."
