Nintendo's little console that could, the Nintendo Wii, surprised the world with its stellar software sales over the past few years. According to analysts at Gamasutra.com however, it looks like the venerable motion based console is losing some steam as of 2010.

The chart below outlines the Wii's twelve worst months of hardware sales since the console launched back in 2006, with four of those months falling in 2010.

According to analysts the Wii software market has seen only one month of year-on-year growth over the past year, with August 2010 the worst month on record for the system. Wii software sales are down an estimated 23% while that of the Xbox 360 remained virtually flat (-1%) and the PlayStation 3 saw an increase of 35%.

The Wii is still the best-selling current generation console to date, but also the system showing the fastest decline in software sales.

Time will tell whether the Wii can hang on to its crown, or whether it's time to make room for the high definition consoles as both the Xbox 360 and PlayStaton 3 receives motion capabilities of their own this year.
