I know practically nothing about Pokemon, so I can't really say what this means. For the incredibly lazy: the developers of Pokemon say that there will be "something different" in the games starting today.  

OMG OMFG I can't wait now, I fuc*ing love pokemon, I wanna know what it is, I hope it's a secret pokemon

Hmm ... that's interesting. I wonder if it's something with the WiFi, because I can't imagine that there is something stored in-game on the cart that hasn't already been hacked, reverse-engineered, or even simply discovered with date-jumping on the DS calendar.

FWIW, according to the sidebar on GameFreak's site, Junichi Masuda's (director of D/P) birth date was January 12, 1968.

A 40th birthday party in the game?

hm i like pokemon but i wouldnt really know what they mean by different,but i guess we just have to wait and see

Perhaps, everyone gets a free

There's been a silhouette of Darkrai floating around on the official Pokemon.com site for a looooong time too ... please be a free Darkrai?! :p

I don't think sarcasm translates well over text...

The Mystery Gift from Nintendo WFC hasn't been utilized yet
