That would make seance Nadav, she could really be in the Evil Queen's castle, take a look at this description of the new trailer from TGS :
BBS Trailer Report From The Light in Chaos
The trailer was the same as shown at DKS3713 except these scenes were added.
Background Music: Fate of the Unknown
Castle of Dreams.
Aqua glances Cinderella running to her carriage, and runs after her.
Cinderella drops one of her glass slippers.
In the world of Snow White.
Aqua looks into a mirror and the figure of the evil witch is projected.
Aqua jumps for a moment and steps back, then plunges into the mirror. (

HALLELUJAH !!!!

)
Aqua's battle scene.
Her fighting style seems like floating.
She does not hold the keyblade, the keyblade attacks as if it knows her intentions.
Sort of like Final Form from Kingdom Hearts II.
Her mode changed to something pink, but the name of it is unknown.
Ven's modes were: Cyclone, Speed Rave, Firebreeze, and Thunder
You could not repeat a mode consecutively.
The items Ven searches for were a white ribbon, lace, and one among two pieces of cloth.
In Ven's level you ride a ball of string, it's kinda scary.
Thunder mode is a temporary name for the official name of the mode. (The blogger forgot the name of it)
Ven's techniques: Attack, Cure, Rush, Fire, Thunder, Fire Blitz, Strike Raid, Final Break, Zero Graviga
When playing as Ventus, in the Thunder mode, you could temporarily use techniques like Strike Raid and Zero Graviga. The finishing moves in normal mode was cure and regular attacking.
When playing as Terra, it seems the main finishing move in normal mode was a freeze attack.
Fatal Mode is an attacking system based on dealing heavy blows.
