What's next for Theatrhythm? It looks like Square Enix is planning something since the publisher filed a trademark for Theatrhythm Final Fantasy Curtain Call in the USA.
Square Enix just released Theatrhythm FInal Fantasy for iOS and it's free. Yeah! Oh, but the iOS release only has two songs "One-Winged Angel" from Final Fantasy VII and "Zanarkand" from Final Fantasy X.
Square Enix Japan teased fans with a ♪ on their RSS feed that links to a new Theatrhythm Final Fantasy page. The site has notes that fly by and says "coming soon."
