The FF&KH blog updated today with a summary of the Final Fantay Versus XIII trailer from the Jump Festa 2008 event in Japan. Everything below is rough translation, blame Google if it's wrong.
The Radio conversation in The Prince's car (cut from the CLOUD DVD trailer) speaks of an ending cold war.Here a part of the translation we can't understand, so we will skip it.
The Prince sees the "Skirt Girl". [See characters page]
"Large" men in black suits are sat around a long table in a "Silver Cathedral" discussing the cold war/current events. (?)
The "Staircase" fight scene from previous trailers is shown. When The Prince walks back inside (At the end of the CLOUD DVD Trailer) he is "ambushed" by the White Cloaked man.
The city changes to daytime in which it seems more medieval (?)
The "Skirt Girl", who seems to be the heroine, is seen having a conversation with The Shotgun Guy while walking down the street.
After their brief conversation the two new characters appear. One of them is rather large (Kanae refers his size to "Mr. 33cm" from Final Fantasy XIII) and another who is dressed much like one of the Turks from Final Fantasy VII.
The Shotgun Guy laughs mockingly at them. (?)
The Prince's car is shown driving through the "wilderness"? Perhaps the baron desert area Nomura has spoken of.
All the characters appear to be in the car with The Prince.[Via FinalFantasy-XIII.net]
A continuation of the "White Robed Man" confrontation scene.
The long table discussion scene is also continued to show another man entering, causing everyone in the room to look over and stop talking (?)
The scene of The Prince fighting the soldiers is continued.
A building is destroyed (?) reminds Kanae of Final Fantasy VII: Advent Children.
A scene between the Skirt Girl and The Prince is shown. Kanae is not sure if they behave like best friends or lovers.
Blue and Red symbols appear behind The Prince and the Skirt Girl respectively.
They look angry at each other, the Skirt Girl unsheathes a sword, the camera pans to her face to show her purple eyes and the Final Fantasy Versus XIII logo is shown, along with a Shakespeare quote shortly after.
