For the week ending ending December 20th, 2008, Nintendo has sold 1,695,940 Wii consoles. 1,000,930 were sold in the US, 695,010 and were sold in other regions of the world (Japan excluded). These numbers are staggering considering the next nearest competitor is the Xbox 360 at 918,919 units for the same sales period. The PS3 pulled dead last at 485,937.
This is nearly a 2:1 ratio against Microsoft and over a 3:1 against Sony.
Also marching along is the Nintendo DS, which missed the 2 million mark in 1 week by under 100,000 units. 1,929,713 new consoles hit the streets, stomping Sony's PSP with a 4:1 ratio.
Nintendo's holiday dominance streak is now at 3 years and counting.
