On Serebii.net, the two extra missions featuring Dialga and Palkia are available now for Wi-Fi download. Sadly, these two missions will not allow you to download those creatures onto your game paks. Good news is that if you own the game, you need to download the first three missions ASAP, as you can get a Manaphy Egg, Riolu with Aura Sphere and a Darkrai to transfer to Diamond/Pearl/Platinum.
There is also another mission featuring Shaymin, but probably will not be available until around February/March in order to get ready for the Platinum version releasing on the DS on March 22nd. The Shaymin mission WILL NOT allow you to transfer it to D/P/Pl. Instead, there will possibly be another Toys' R Us event around February/March that will allow you to download Shaymin to your games, and if this 'special' Shaymin is traded to Platinum, you can unlock a flower that transforms Shaymin into the Warrior form (Grass/Flying). Plus there is a Regigigas you can download during that event, MAY BE, and it will allow you to unlock the 3 Regis on Platinum ONLY. Yet, once you unlock the 3 Regis on Platinum, you can unlock the Regigigas on that game as well, and it's at the pitiful level of being Lv1. YES, Lv1.
Anyways, be prepared and download the missions, and check Serebii.net for news on these missions and events.
