Theatrhythm looks like it'll be pretty cool, but I think that'll depend on what kind of RPG elements it has. If I have the opportunity to gradually progress characters through stat-gaining and/or equipment-gaining then I'm all for it. I'm fine if it is the western name for this game, though.

I don't really know how they divide their development team resources, but I'd rather just see them focus on other IP for smaller titles and leave Final Fantasy to bigger titles like Versus, XIV 2.0 and XV. That's just me though.
