I know that for a fact if it is anything like FFX then it will be one of the best games ever. I loved FFX and I was addicted forever. I have seen pictures of the new characters and have heard about the system that they are bringing back, and it sounds killer! This game (FFX-2) will be revolutionizing for the Final Fantasy games and PS2. I can not wait! :)
The new system I have read has a choose your own job kinda thing, just like FFV. (ie. You can have Auron be the white mage, instead of being the in your face get out of my way guy.)
And personally I don't like Yuna being a weak little girl, that is Rikku's job!
