Times are changing. For much of the last decade, Nintendo, Sony, and Microsoft have fought for the hearts and minds of video game players worldwide. From 2001 to 2009, the results were the same:
Either Nintendo or Sony sold the most units of video game hardware (portables + consoles) in every important world market. Whoever didn't sell the most finished second.
With only three players for video game hardware, Microsoft was locked in third place when it came to total units of hardware sold. But the old order now appears to be cracking in the Americas, and particularly the United States, even though the Nintendo / Sony lock on first and second place for total hardware sales will remain intact on a worldwide basis.
