They're going to dub it for sure?

Well, I admit, I'm definitely assuming that there will be. Last I heard, they were talking about it. Truth be told, I'd be amazed if they didn't. For all of fandom's nonsense, IY was a popular series, and they'll cash in on that if they can.

if life can leave me alone long enough to actually let me turn my squee into something useful *facepalm*

The dilemma every fanfic writer must face, no? =P
