The Jirachi Gamestop event was confirmed today and will be coming February 27th to March 13th(dates subject to change) to a local Gamestop near you(most likely US only though )

This Jirachi will know the special dragon-type move: Draco Meteor, and when traded to a copy of HeartGold or SoulSilver, it will unlock the special Pokewalker course, Edge of the Night Sky.

I hope all the events they're doing now will also be available through Wi-fi for the American HG/SS.

"Ending March 13" reminds me of the Regigigas event last year, which lasted all the way up until the day before Platinum released.

It'd be a lot easier if they did these events the day the game came out to create hype,

Hmm. Hopefully the events will be distributed over Mystery Gift/Wi-Fi in case I miss 'em.

I've always wondered about whether the events actually come to Hawaii, since it's, y'know, Hawaii.

This sounds interesting seeing how Jirachi is the only legend I don't have.

Hurray, another event pokemon! It would be cool if they had a Pokemon event every month, even if it was just a regular Pokemon with a special move or two.
