It's neck-and-neck but Nintendo looks to have just slipped past Microsoft in terms of total US sales for current generation game consoles. What's more, it's pulling away with a 3:1 sales lead for the month of June. NPD Group reports more than 666,000 Wii consoles were sold in June compared to 405,500 PlayStation 3s and 219,800 Xbox 360s. That makes for a total of 10.9 million Wiis sold in the US since it launched in November of 2006. Impressive. Even more so considering that Microsoft had a one year head-start to reach a second place position of about 10.4 million US console sales.
