The January 2012 issue of CoroCoro has announced that a brand new Pokémon game will be revealed in next issue of CoroCoro which will be released in Japan on January 14th, 2012. Further information regarding the game was not released other than it will be a shocking announcement.

Also announced was a special alternate colored Dragon eggs event at the Pokémon Center's to commemorate year of the Dragon. Players of the Japanese versions of Pokémon Black and White can visit the Pokémon Center's and receive an egg each week for four weeks. The four distribution periods are: 1: January 6th, 2012 to January 15th, 2012, 2: January 16th, 2012 to January 22nd, 2012, 3: January 23rd, 2012 to January 29th, 2012 and 4: January 30th, 2012 to February 5th, 2012. Players will randomly receive one of six different Dragon Pokémon. The six Pokémon that will be distributed are: Tattu, Nuckrar, Tyltto, Tatsubay, Crimgan and Monozu.

As far as the new game goes i really can't wait! i'm so anxious lmao.

One thing's sure, it won't be a brand new game (aka: new generation), as they're far from being done with the V one so far (as far as the anime/movies are concerned, and we all know they 'work' together).
It may be the infamous Pokémon Grey, though I'm not sure whether it'd be on DS and/or 3DS.
Or maybe a 3D game, like Stadium/Revolution or Colosseum.

It's probably gonna be for the 3DS.

Yeah, I think so too. I just hope it'll be something more inspired than Super Pokémon Scramble, which could really have been put on the e-shop instead of a full-fledged retail release...

Anyway, I'm really looking forward to the announcement.
