The US price is $250 (£133) and the Japanese price is 25,000 yen (£113).
UK and European launch details will be announced on Friday, with hardware price finally set and plenty of good news for retail regarding stock.
The launch system will come with Wii Sports, which features tennis, golf, baseball and bowling.
Games available pre-Christmas will include Legend of Zelda: Twilight Princess, Excite Truck, Madden NFL, Red Steel and Tony Hawk’s Downhill Jam.
Reports suggest, however, that the new Mario game for Wii will not be released until 2007.
Nintendo hopes to sell six million units of the Wii console by March.
