The PlayStation 3 version of Square Enix's upcoming MMO, Final Fantasy XIV, was reportedly pushed back to March 2011 due to technical difficulties. Speaking with VG247, producer Hiromichi Tanaka explained that it mostly due to the lack of memory on Sony's platform.
"The main reason was memory," said Tanaka."¨"¨
"On the PC, they have enormous memory. For PS3, there's a restriction."¨"¨"They are adjusting the memory size and customizing it; it took longer than we were expecting. But we're really working hard to bring it out as soon as possible."
