Are the sales figures for the Xbox 360 Accurate?

Xbox 360 is overtracked. It sold about 10mil. PS3 sold about 40mil (so PS3 was undertracked).

Aren't you shorting the PS3 another 10 milion sold?  I thought it was 50 million and slightly ahead of Wii.

The PS3 is getting another price cut to $150 next week and it'll sell, maybe beat the Wii in no time.
