as i dont have a ps3 yet iwould say no, but it is a good idea.
but even tho final fantasy is a huge franchise, its not as big as the sporting games and other such things. of all the people i know, only a hangful who have played the games a dozen at most and only 1 other has played them all.
so for it to be an exclusive game to help boost sales of the ps3 just isnt smart if sony want to make any money.
BUT final fantasy should
NEVER go on any other console, no matter wat ppl say about how the other consoles have this and that. blah blah blah
