UPDATED - JIRACHI IS HERE!! Visit your local GameStop between February 27 and March 13th to download Jirachi into your Pokemon Diamond, Pearl or Platinum game!
Details from Pokemon.comFrom the screenshot, it looks like Jirachi is at level 5, but the site doesn't give any details about its nature, item, etc.
And if you trade it to Heart Gold or Soul Silver, you can unlock a special Pokewalker route called Night Sky's Edge!

From Pokemon.comSince I didn't see this posted previously, I thought I'd give you all a heads up. There aren't many details so far, but the GameStop logo suggests that you'll have to visit the store to download Jirachi to your Diamond, Pearl, or Platinum games, but there's no date yet.
According to the site, this Jirachi will have "unique moves and items" and apparently something special will happen if you trade it into HeartGold or SoulSilver.
This thread will be updated as soon as we get dates. Please post any Jirachi-related announcements or discussions in this thread to keep the forum nice and tidy.
smile EDIT BY CATPIAN:upon finding the dates and detail i will send a guild-wide announcement
