Continuing the recent barrage of sales numbers and their numerous interpretations, the sales-tracking firm NPD Group informed IGN that the Wii had the highest software to hardware sales ratio across the past holiday season.

During December, North American consumers bought an average of 8.11 Wii titles for every Wii console sold in that timeframe. The Xbox 360 ratio was just a bit lower, coming in at 7.76 games for every unit, while the PlayStation 3 moved 5.04 games for every piece of hardware.

The Xbox 360, meanwhile, has dominated the lifetime ratio with an impressive 7.0 attach rate since launch.

Despite the Wii's impressive holiday figure, its overall lifetime ratio is substantially lower. Since launch, Wii software has only sold an average of 4.64 pieces for every unit. The PlayStation 3's holiday numbers more closely match its overall figure, which is 4.26.
