Here some new information are out of the current editions of the Japanese periodicals Famitsu, Famitsu PS2 and The PlayStation 2
Summerized information from Famitsu Weekly Magazine:
- the man in the white robe probably has something to do with "Planet Scar Syndrome" ("Geostigma" in US version?)
- many people suffer from PSS, especially children -- the reason is unknown
- Tifa seems to work in "Seventh Heaven" again
- Vincent seems to know something important about the events in Midgar
- one of the magazines guesses that the enemy trio (Kadaj, Loz, Yazoo) is told by the man in the white robe to attack Cloud
- the trio refers to somebody as their "older brother" -- according to Nomura, it's one of the film's big mysteries who this person could be (he doesn't really answer the question whether it could be Sephiroth)
- Kadaj, Loz, and Yazoo are brothers, you could also call them "Advent Children"
- Kadaj can be calm and ferocious, childish and intellectual
- Yazoo is "aloof from the world," one could say
- although Loz doesn't look like that, he's rather childish, maybe a crybaby (all according to Nomura)
- the relation between Cloud and Tifa will probably become important, too
- Kadaj seems to be the key to the film's story
Famitsu will have more info at the end of June -- more details about the Turks, they say.
