As many of you remember, Japan has an online game to win one of the 7 eevee-lutions and be able to transfer it from the Dream World to your copy of Pokemon Black or White. Pokemon.com is doing it as well, although the game is slightly different and you can choose which evolution you want =] Please note that you will NOT be able to re-choose and is locked to your Pokemon Trainer Club / Global Link username.
You can read about it here.
ps- Glad SOMETHING noteworthy popped up. I need news to post ;__________;
