According to IGN and Kotaku...
June 5, 2007 - Looking for more Final Fantasy following the Xbox 360 port of Final Fantasy XI? Then you're going to have to look to a different next generation system. A Square Enix executive has disclosed to Japan's Nikkei BP that the company currently has no plans for Final Fantasy games on the 360.
Noting that the PS3 is getting Final Fantasy XIII, the website asked Square Enix's Shinji Hashimoto if the Wii or Xbox 360 will also be getting games in the series. "For the Wii, we have FF Crystal Chronicles in production," replied Hashimoto. "As for FF on the Xbox 360, it's currently a completely blank page."
Strong words from Hashimoto, although perhaps if everyone goes out and buys Last Remnant (that includes you!), Square Enix will have a change of heart.
From what it sounds like there may not be a FF game on 360 for at least a few years... But this is a bold move by Square-Enix... Considering how sales are going, Square-Enix could make a lot more money putting it out on both systems... I'm sure a later released port of the game is an option but im sure Sony had their hands in this decision... If MGS4 stays on the PS3, then it will help Sony a lot... Looks like Rob/Skie and many other people (including me) are getting PS3's...
The thing that gets me is the vast amount of Xbox fans flipping out across the net with racial statements and claims that Final Fantasy is and always was a "lame" game... I highly doubt they would be saying this if the news were different...
