Square-Enix are laying the blame for the delayed release of FFXIV on the Xbox 360 at the feet of the consoles online service.
Pop quiz time; what platforms is Final Fantasy XIV coming out on? If you said "Just the PlayStation 3", I'm afraid you get a big fat 'F', because despite what Jack Tretton might have said about the game at E3 this year, it's about as far from a Sony exclusive as you can get.
At Gamecom, Final Fantasy XIV Producer Hiromichi Tanaka stressed that an Xbox 360 version was in the works, and blamed Xbox Live for the delay that will occur between the PS3/PC release and the game's appearance on the 360.
"... for FFXIV, because 360 has its own policy with Xbox Live that is different from [the] internet, that's something we're in discussions with Microsoft [about], to come to an agreement. That's one of the reasons it's not going to be launched at that point."
The odds of the two companies coming to an arrangement are pretty good, as Microsoft are unlikely to want to let such a massive franchise pass them by.
