It appears that the Theatrhythm series is now a viable franchise for Square Enix as they recently announced a third game in the series—Theatrhythm: Dragon Quest, which, of course, is also the first game in the series not to be based on Final Fantasy.
Not a whole of info has been announced regarding the title just yet, though the rhythm RPG-based gameplay is expected to remain largely the same. No release has been mentioned for Western territories just yet either, though based on the previous installments' success, it is likely that the West will see it localized.
For now, Theatrhythm: Dragon Quest is slated for release on 3DS in Japan on March 26, 2015.
What do you think about Dragon Quest being chosen as the basis for the next Theatrhythm game?
