The next Pokemon game is coming out fractionally earlier than the US release.
Pokemon Black and White will be coming to Europe on March 4, 2011. This is just two days before the US release date of March 6.
Additionally, Nintendo released an image of the Pokemon Black special edition Nintendo DSi. Bundles for each game were released in Japan around two months after the initial game release. The DSi still features artwork of both Legendary Pokemon, but now has just "Pokemon" printed on the front rather than "Pokemon Black".
