During the Japanese Nintendo Direct presentation today, a version of Atelier Rorona was announced for Nintendo 3DS. Not much is known at this point, but we can see the 'chibi' graphic style returns. One of the images also shows grid-like battle system, so we might expect the 3DS version to play a little different from Atelier Rorona and Atelier Rorona Plus.
The game is set to launch in Japan sometime in 2015. You can see the original Nintendo Direct announcement below.
