The picture is changing quickly. In the fall there was an article about attach rate. It was something like 7 games per Xbox, 5 games per Wii and PS3. In December, Wii outsold Xbox 8 to 7 (I had to read the statistic twice because it's 8 games per system _sold that month_, not 8 per system in existence).
