Ok here is the FF Versus XIII trailer from Advent Children complete....

Now if you pay attention at certian points it says things in italian/latin.

I am going to attempt to translate them. I am also trying to find someone who can translate japanese for the talking scen at the end...

il cammino per i cieli= the path to the heavens

la morte e la dea=death and the goddess

la stella incontrata di notte= the star met her at night

le memorie de morte=the memories of death

Found Translation for Noctis/Stella /Shinmegami conversation....

Stella: Mr. Noctis, you're looking at that light, aren't you?
I am too.
This was the light that we saw from the bottom of the staircase.
Noctis: That's right. When did you start seeing it?
Stella: Since I was a child.
Noctis: I guess that means you're dying.
Stella: Yes. Are you also dying?
Noctis: My bad.
Stella: The Goddess Etro greets the souls of the deceased and opens the door to the afterlife.
When that door opens, the released souls burst out in a streak of light that ascends to heaven.
However, very few people are able to see that light.
Those who can see the light are given power from the Kingdom of the Dead.
At least, that's the Teneprae legend.
Noctis: It's the same here.
Stella: Mr. Noctis, have you been entrusted with that power?
Noctis: Nope, I don't need it.
It's just not my style. (??? sorry, the first Kanji is too blurry on the video I'm using)
Stella: I see.
Even though it's an amazing power, but you need to sacrifice someone to get it.
Doing that would give you nightmares.
Noctis: Doesn't matter, it's just a silly fairy tale.
Still, it'd be a good idea not to talk to anybody about the light.
Stella: Why not?
Noctis: Because it's a pain in the ass to deal with people who are different.
Stella: But if the Tenepraeian legend is just a fairy tale, what is that light?
Noctis: It's just something that there, and let's leave it at that.
What's your name?
Stella: I'm Stella.
Noctis: Stella, I've got to go.
Stella: Sorry for taking up your time Mr. Noctis.
Noctis: You can call me Noc.
Stella: I've got to get back as well.

Stella: I have a feeling that the light gave me power tonight.
It gave me the opportunity to speak with you.
Noctis: You're going to have nightmares.
Stella: Mr. Noctis, you're such a kidder.
Noctis: Call me Noc.
Stella: Next time we meet I'll call you that. Please come to Teneprae so that I can show you around.
Noctis: Might be nice. I'll think about it.

??????: Who... are you?
Noctis: That's my line.

there already a translation floating around.

the story looks very interesting.

this is a fantasy based in reality

il cammino pericieli - something about a way
la morte e la dea 
la stella incontrata di notte
le memorie di morte

final fantasy versus 13

there is nothing good or bad but thinking makes it so

its here in vgchartz but can't recall what thread, they see some kind of light, that it's some kind of door of death.

the game main focus looks like it's death.

and some power they obtain by sacrife someone beloved.

@Jo
Oh, didn't know that. I just figured I would start a thread pretty much to speculate what it could all possibly mean as pertaining to Versus's story.

yeah i think its in the stream thread but i am too lazy to find it. x.x

i found the translation from a forum on gamespot. I put it in the OP.

Translation of the conversation of Noctis and Stella

^ok. I pretty much cut and pasted the whole thing from Gamespot lol . I geuss I should proofread...

Noctis seems cool

From what I am getting from it so far.....
Stella and Noctis both have the same gift
Whatever gift they have, is slowly killing them.
There is someway to increase their power or ability(maybe to keep them alive) but they have to sacrifice someone close to them in order to do it.
The Shinmagami can seemingly speak to Noctis(and Stella?) in their heads.
There may be more then one shinmegami. Stella says it told her something.....We actually hear Noctis's say "Who....are you?"
