So what if Square Enix isn't gracing the PS3 with a game until 2008? So what. Final Fantasy XIII is married to PS3 hardware. Just listen to Square Enix character creator Tetsuya Nomura (above, into jewerly) drone on about the PLAYSTATION 3:
It's not just about how pretty the graphics are but more of how much limited amount of movement we can put in one go and how big our imagination and ideas are. The PS3 is the machine that is closest to being able to express our imagination.
See, the PS3 is not expressing their imagination, because Square Enix's imagination is way too big for that. Just look at all the games they release! Rather, the Sony console is CLOSEST to achieving that. And for you to play Square Enix's immense imagination, you're going to have to wait, not rush things and take it nice and slow.
