Theatrhythm may be about to take an encore if a new Square Enix trademark is anything to go by. As spotted by Gematsu, the Japanese mega-company registered a US trademark for Theatrhythm Final Fantasy Curtain Call on August 27.
The trademark itself is identified for several properties including game software and music CDs, but beyond that there's not much to go on. The name could apply to so many things: a new game, a new platform, a revamped re-release of the 3DS and iOS game... I could go on, but I'd just be exhibiting my ravenous hunger for more Theatrhythm - reasonably priced Theathythm, mind you.
