Yes, but the box set of doom that features "On the Way to a Smile" has been out for about a year now. I'm pretty sure it's Stateside, too. I could be wrong though. Maybe it's still only in Japan or, even more absurdly, they're selling it in Kanji in the states.

I think a lot of fanfic writers might ignore it, though because it's ben a widespread rumour or misconception that it was written by a fan or something. Also a lot of fanfic writers are lazy and don't like their fanon being fucked with. I mean, think about Nekojita's massive personal fanon and think how badly it's been fucked with this new information.
