Reportedly, the darker colored console will come packed with a copy of Wii Sports Resort and the Wii MotionPlus add-on required by the game at $199.99. That's the same price the existing white Wii, which only comes with plain old Wii Sports, currently carries. However, Warlmart offered a similar bundle--including a white Wii, Wii Sports, Wii Sports Resort and Wii Motion Plus--earlier this year at $199.99.
Though Nintendo has yet to release anything other than the white-colored Wii in North America, the company has released multiple colored accessories alongside their standard white iterations, including black Wii Remotes with black Wii Motion Plus add-ons, pink Wii Remotes, blue Wii Remotes, and a black Classic Controller Pro.
I heard that Black Wii's are bigger then White wii's
