Enterbrain and Famitsu have provided a first week sales figure for Pokemon Black & White 2. The DS game sold 1,618,621 in its first week of sales. As the game was released on a Saturday, the "first week" includes just two days.
Black & White 2 ended up with the third best start for the DS platform. It's also the first game to sell a million units this year, on any platform.
Not bad for a follow up on B/W games and the second best sales for the first week in the franchise.
