For the first time since it hit the American market, the Nintendo Wii can claim to be the most popular console in the United States. Overtaking the venerable Xbox 360, the Wii now has the greatest lifetime penetration of any next-gen console currently available. 10.6 million Wii’s have been sold, compared to 10.5 million Xbox units. Given the Xbox’s considerable head-start on sales numbers, this is a particularly impressive feat. Sure, the upcoming Xbox 360 60GB might help Microsoft gain some ground, but given Nintendo’s steady progress, we’re pretty sure the company will continue to prove a formidable opponent to both Microsoft and Sony. Wait, who’s Sony again?
