Translation of all the dialogue in the versus trailer:
Driver: Prince Noctis. (Several times)
Driver: That over there's intense isn't it?
Noctis: It's just like an occupation.
(Tool booth says that it's closed, but they get to go through anyway since he's a prince.)
Noctis: Goodbye, whoever you are.
Lady: You see the light too, right Noctis?
Lady: So do I.
Lady: When the goddess Etro opens the gates to welcome the souls of the fallen, the dazzling light that lights up the land of the dead leaks out into the heaven.
Lady: Sometimes there are those that can see the light. These people are gifted with powers from the land of the dead.
Lady: Did you receive any powers Noctis?
Noctis: I don't know about Etro's light or whatever, but I don't like seeing that.
Lady: But why... why are there people who can see it and people who can't, I wonder?
Lady: I believe that there is some special meaning to it, and I've been thinking about it for a long time.
Noctis: A meaning with.. seeing the light?
Lady: Yes. For example maybe there is something I must do or accomplish?
King: I see, so you are just using it?
King: However, I'm sorry to say that you can not become king.
King: I will not turn over the throne to anyone.
King: I will go down in history as the last king
Noctis: Ignis, how was it?
Ignis: L'cie(?) were continuing as if nothing happened. They continue to thrive together with the crystal.
Ignis: I believe that this is the best way it could end for the Niflheim side. (There's some word that sounds like like Hanawa.. but I don't think it fits in. Might be referring to some in-game thing that I/we don't know anything about.
Noctis: That means we will do a full assault and recapture the crystal, right?
Ignis: No, look at it realistically Noct.
Noctis: You saw my strength, didn't you!?
Gladiolus: We saw it, but your body isn't used to your new power yet. I must be tough right now.
Ignis: You're going to need time.
Grumpy: Let's go!
Noctis: Why should I, the strongest of us all, run away?
Ignis: When you're here the number of victims will increase.
Ignis: You're their target. They probably want to take you hostage and use that advantage in negotiations.
Noctis: Negotiations? At this stage?
Noctis: I'll just beat them all.
Ignis: Noct, I'm sorry but you're just not strong enough.
(DRAGOON! HELLZ YEAH!)
Ignis (I think): Do you have a plan? Something 10 times worse.
Noctis: I'm going to think of a way to return it hundredfold
Translation of the video explaining the mythology:
Once upon a time, a god ruled the world. He was called Buniberzei.
Buniberzei defeated his mother, the goddess Muin, and took control of the world for himself.
Muin disappeared into the unseen world--the invisible world.
Buniberzei was a god with many troubles.
The world, it was certain, was destined to die.
He believed this was a curse laid on the world by his mother Muin. Buniberzei knew he had to destroy her.
To do this, he must search for the door. The door to the invisible world where his mother waited.
Using his will alone, he created the first falâ€™Cie.
First, he created falâ€™Cie Pulse.
The duty he laid on him was to open the world, and search for the door to Muin.
Next, he created falâ€™Cie Etro.
But it was a mistake. Unknowingly, he created her exactly in the image of Muin.
Buniberzei feared her, and gave Etro no power of her own.
Instead, he created falâ€™Cie Lindzei.
The duty he laid on him was to protect Buniberzei from all who might seek to destroy him.
Buniberzei gave Lindzei one special duty. To wake him once the time came.
Then he turned to crystal, and fell into an endless sleep.
Pulse wished to expand the world, so he created many falâ€™Cie and lâ€™Cie.
Lindzai wished to protect the world, so he created many falâ€™Cie and lâ€™Cie.
But Etro was powerless, and could do nothing of her own.
Lonely, she thought of her mother, who she so resembled.
Etro tore at her body, letting her blood flow to the earth, and disappeared from the visible world.
From that blood, torn from her body, sprung humankind.
Creatures that were born, only to die.
The destruction of the visible world was no curse, only fate.
The world was divided into two halves, the visible and the invisible.
If the balance between these two were destroyed, the world itself would be destroyed.
The goddess Muin could do nothing to stop this fate.
She was being swallowed into the chaos of the invisible world.
Just before her last moment, Etro came to her side.
Muin told Etro that she must protect the balance of the world, before slipping into the chaos forever.
But Etro was foolish, and didnâ€™t know the meaning behind Muinâ€™s words.
Etro was lonely, but she felt affection for those humans who live only to die.
As they died, she smiled, and gave them chaos.
The chaos Etro gave them, the humans named â€œheartâ€.
Their hearts would become their power, but the humans did not yet know this.
Soon, they called Pulse the all powerful ruler. Lindzei they named their protector, and Etro... Etro the named â€˜deathâ€™.
The humans lived on the world, hold chaos inside them.
Because they held chaos so close, the world once again was in balance.
And Buniberzei still sleeps. A crystal.
Until the end of forever...
