Well Microsoft now has a new deal with Square Enix so you're in luck. Why? Because ff games are now in production.
As for the ps3, the trailers are all bogus. Do not base your decisions off that garbage. It's all generated on completely different systems and NOT in realtime.This is what sony does to hype up their product. I'm not saying sony sucks, I'm saying becareful because their good at what they do and you dont want to be stuck dropping 500+ dollars on a system that really isnt THAT great.
Cause I garuntee you, NONE of these next-gen systems will be what they promise to be. It's too soon IMO.
