Blu-ray was already outselling HD DVD in terms of stand-alone players by about a 60/40 margin during the month of December – despite the fact that HD DVD players were considerably cheaper. But that split has grown dramatically following Warner Bros’ decision, according NPD unit sales data compiled by Digital Bits.

According to the charts, over 92.5 percent of buyers chose a Blu-ray device while less than 7.5 continued to buy HD DVD equipment. This does not include Sony’s PlayStation 3 console, which is believed to skew results further in favor of Blu-ray. Although the data only reflects one week of sales, the trend certainly isn't promising for backers of HD DVD technology and the many people who invested on HD DVD equipment.
