pokemon x/y

Been waiting for an excuse to get a 3DS (or 2DS, or an XL)? Here's your chance! If you register a system and a game, you'll get a free digital download code for either Pokémon X or Y.

The story is set in Diamond Ore Country, of which Diancie is the princess.This is a country located deep underground, where the Pokémon Carbink live together in peace. The energy source of this country is a giant diamond called the Sacred Diamond, which can only be created by princess Diancie. However, the current princess doesn't yet possess the power to create such a diamond, and the current Sacred Diamond's power is soon going to run out, which would result in the end of the country. Diancie meets up with Ash and Pikachu, and set off together with them to search for the legendary Pokemon Xerneas, which possesses sacred power, but on the way, they find the cocoon where the Destruction Pokémon, Yveltal, who was said to have once destroyed life in Kalos, lies in wait.

From the announcement:

Nintendo and The Pokémon Company International have postponed the launch of Pokémon Bank and Poké Transporter - two software applications that were originally scheduled to launch for Nintendo 3DS on Dec. 27 - due to a large volume of traffic to the Nintendo Network service. Due to the high traffic, players are having trouble setting up Nintendo Network IDs and downloading content in the Nintendo eShop on both Wii U and Nintendo 3DS. We truly regret the inconvenience, and wish to reassure everyone that providing a solution is our top priority. We apologize for the delay and thank you for your continued patience.

Starting December 6th, head to Target for a red 2DS and Pokemon X, or Toys R Us for a blue and Y bundle for $149.99. Why on earth the blue version of the game comes with the red version of the system is unclear, but supplies are limited so plan accordingly.
