The Pikachu-themed version will have a yellow exterior and a white interior with Pikachu on the top. Once Japanese fans place their pre-order for the console, they will be able to pick it up on September 15th.
Currently, there is no word if the console will be available outside of Japan. Should it prove very popular, it is possible (according to our sources) that Nintendo could elect to release it in the North American and European markets, but currently there are no plans to do so.
