The latest console-sales figures to be released from NPD Group reveal that the Wii has overtaken the Xbox 360 in being the most purchased console in the US.

Kojima Productions' Metal Gear Solid 4: Guns of the Patriots lead the way on the software side with nearly a million total units sold, while the Nintendo DS and Wii continued to dominate hardware sales.

According to Nintendo, today's data shows that the overall US install base for the Wii is nearly 10.9 million units, making the Wii the "new console leader in the US" and reaffirming it status as the worldwide console leader.

Taking today's figures into account, the Xbox 360 has sold a total of 10.4 million units in the United States since launch. As of April 2008, the Wii had sold 24.5 million units worldwide, while the Xbox 360 had moved 19 million.
