I haven't seen info on this here yet, so; the first trailer is out! I'm highly interested in this. Too bad we'll probably never see a western release, if things go as they usually do.
 
It's not much, but at least it gives some set-up (which is translated in the description it seems), and a few seconds of motion. We still don't really know how it'll play though:

Billed as the PlayStation 3's "first animation RPG," the game revolves around an 18-year-old knight, played by Tsubasa Yonaga (Chihayafuru's Tsutomu, Big Windup!'s Ren). The knight is about to marry the Kamuza Kingdom's 16-year-old sorcerer princess named Toki, played by Kana Hanazawa (To Love-Ru's Mikan, Steins;Gate's Mayuri). However, Toki learns from a fortuneteller that someone will attack the two during their wedding ceremony.

Satelight is not just "hand-animating" the key cut scenes (as many role-playing games have already done in the past), but also the characters' movements and battle sequences in regular gameplay. The single-player fantasy game will ship this year for the PlayStation 3 console at a price to be announced later.

The anime studio Satelight (Macross Frontier, Aquarion Evol, Mōretsu Pirates, AKB0048) is animating the game in collaboration with the production company Bandai Namco Games and popular Japanese role-playing game developer Imageepoch ( Fate/Extra, Luminous Arc, 7th Dragon).
