The U.S. console hardware sales results in 2010, as collated by NPD, appear to show a market in flux. Both Sony and Nintendo have reported that they are experiencing supply difficulties with their systems, the PlayStation 3 and Wii, respectively.
Sales of the Nintendo Wii rebounded slightly in March, up 3 percent over the rate it averaged throughout January and February. This could signal an easing of the supply constraints Nintendo had noted or it could simply be a small statistical variation.
On the other hand, PlayStation 3 sales were down 20 percent relative to the rate established throughout January and February. Sony first mentioned in mid-February that it would have trouble supplying enough PS3 hardware in the "coming months".
