I still don't understand why they haven't made them available on the eShop. They put those crappy Dreamworks Halloween shorts on there for, what, $2 a pop, and we can't get the Kid Icarus anime, which people actually want? It's like Nintendo just wants to torment us, or is suddenly allergic to money; we all know it'd sell like gangbusters.
Then again, maybe that's their strategy: keep it out of reach for so long that when they do put it up for sale, gamers will snatch it up like water in the desert. That's worked well enough for Disney in the past.
