Last year, in Japan, the official site compiled a poll which allowed you to vote for a Pokémon, the winner is then given over the Global Link. In Japan, the winner was Arceus and in Korea, it was Rayquaza. The Pokémon given are distributed with their Hidden Ability, provided they have one. Now, this promotion is being done outside of Japan. You have until November 30th to vote for one of the 493 pre-Unova Pokémon with the winner getting revealed on December 13th 2011 and distributed from February 1st 2012. You can vote for this on the official site here. We'll bring details on the winner as soon as possible
