I think it got pushed back... you'd have to ask Takuto-kun that, I'm just working on the sets! [[a touch apologetic there]]

And there's some people who can tell by looking, but I think it's pretty rare. There's a machine in Shibunsen that can show it, sort of like an X-ray, and I think I saw some hand held ones there last I was by too... If you can find someone who knows how to use those, you can find out that way.
