We know that it was hard to miss the demonstration of FFXIV in 3D earlier this year during E3 if you've been keeping up with FFXIV news since day one. It was only a proof of concept at the time, a tech demo to show that it was possible, not exactly a confirmation that they would be doing it. Recently sites began reporting that FFXIV would in fact be fully 3D supported on the PS3. It's been discovered that's not the case and that FFXIV in 3D won't be happening any time in the foreseeable future after all.
Producer Hiromichi Tanaka was quoted as saying, "That isn't something we are considering right now when questioned in a recent interview about the possibility of 3D in FFXIV. It would be fairly difficult." At the very least, that's a clear indication that we won't be seeing FFXIV in 3D any time soon. Thanks to ZAM for the official word on this.
