Translation of the trailer:

Text at the begining -

The world has been created 12 times, and the 13th time is beginning
Reality and destruction, are not defined by the Creator
That is decided, by each and every person who shares this world

And the in-battle dialogue -

Garland: Understand that there can never be harmony (I'm not 100% about that line, so that's only a loose interpretation. Sorry =\)
Garland: For eternity I will fight against fate!
Warrior of Light: It is fate that this ends here!

Kuja: I shall perform for you, your own requiem! Hahahahaha!
Zidane: After that, the climax!
