writes "Nintendo today announced the Wii sold through more than 600,000 units in the Americas in just its first eight days of availability. That's a rate of nearly one per second continuously since the November 19 launch!"
From the article: "The company noted that, when taking into account first-party software and accessory sales, Wii sales have thus far amounted to an impressive $190 million. Nintendo also added that sales of the Wii's highly anticipated launch title, The Legend of Zelda: Twilight Princess, has already has achieved sales of more than 454,000 units in the Americas, a figure which it notes represents in excess of of 75 percent of all hardware purchasers."
I couldn't find any sales figures for the PS3, just word that the company has sold all the units it shipped
. Gamasutra is also reporting sales figures via Ebay
for the two consoles. 15,000 PS3s were sold, while the Wii cracked 27,000 via the popular online auction site.
