Announced by whom? TPCi hasn't announced it on any of the Pokemon websites outside Europe, and they never will. It's downloadable elsewhere thanks to a quirk in the Mystery Gift programming.
Hey, maybe I should make a "Jirachi available in New Zealand" news?
This is just stupid, and if it had to be made, why don't make it right? Include all the places that can get it if you absolutely have to make useless "news".
