This appears to be the same promotional video that was shown to audiences at Game Dengeki Appreciation Festival 2011 back in March.

The third PS3 Atelier game and the 13th overall entry in the series (15th if you count Mana Khemia 1 and 2) will have players taking control of Meruru, the student of Totori from the previous game. It is said that this will conclude the Arland storyline that started with Atelier Rorona and continued with Atelier Totori.

Atelier Meruru is currently set for release on June 23.
