A few months back, Japan was set to get a rhythm based Final Fantasy game called Theatrhythm. This featured songs from Final Fantasy all the way to XIII or XIII-2 with DLC. Beyond just being a rhythm game, it also adds a combat element to spice it up. After a successful Japanese release, it was only a matter of time till other regions get it.
After a long wait, it has finally been announced for US and EU release. Currently it is set for release in Summer 2012, but no further details were given. Stay tuned to JustPushStart for more information as we get closer to release.
