While currently on an interview and promotional tour in the United States for the upcoming Pokémon Black and White games, GameFreak Director Junichi Masuda revealed to 1UP that the rumor that originated on IGN about Pokémon Black & White having additional features if played on the Nintendo 3DS was not correct.

"Other than just being able to play the game normally, there's nothing special if you use a 3DS." Masuda confirmed in an interview at Nintendo's office in Redwood City on February 15th, 2011.

Masuda also posted pictures of his visit to the Pokémon Black and White Version Tour at Westfield Oakridge in San Jose, California on his Director's blog on the GameFreak Director's Column blog.
