Wii tie ratio 8:1 in December, still trailing life-to-date
The Nintendo Wii saw a surge in game sales in December, with NPD Group reporting (via IGN) the software to hardware tie ratio for console reached reaching 8.11 for the month. That means approximately eight games were sold for every Wii console sold during the month. Top software sales for Wii in December include Mario Galaxy (1.4 million), Wii Play (1.08 million) and Mario and Sonic at the Olympic Games (633,000).
It should be noted that the 8.11 statistic doesn't reflect the overall tie ratio -- if 7 people who already owned a Wii bought Mario Galaxy and an eighth person bought Galaxy and a Wii, the figure still holds -- but it does boost the console's life-to-date tie ratio, now resting at 4.64.
The tie ratio for PlayStation 3 was 5.04 in December and 4.24 life-to-date, while the Xbox 360, with one year ahead of its predecessors, still holds the dominant position with 7.76 in December and 7.0 overall.
