Like Keldeo before it, Meloetta may be available as an event Pokemon. We still don't know for sure when it'll be available.

Straight from the FAQ:
How do we get Keldeo?
The Keldeo event is through wifi, starting on Japanese games from June 23rd - August 31st 2012.
This Keldeo is level 15 and has Aqua Jet, Sacred Sword, Close Combat and Hydro Pump.
How do we get Meloetta?
The Meloetta event occurs as part of a movie 15 giveaway, starting on July 14th 2012.
This Meloetta is level 15 and has Quick Attack, Confusion and Round.
English versions of both Pokemon have not been confirmed seeing as the games won't be out internationally for a while.
