Sony hasn't disclosed the raw number of PlayStation 3 units it sold last week. (A Sony spokeswoman says it will give those numbers when NPD Group stats come out in mid-December.) The company did say that PlayStation 3 hardware sales were up 245 percent last week, when compared with the same week last year, among the top 10 North American retailers. This morning, Microsoft said the Xbox 360 still outsold the PS3 two-to-one last week, according to "estimates from top retailers."
Update, 12:30 p.m.: Sony is disputing Microsoft's statement about the ratio of Xbox 360 to PS3 sales. Here's what Kimberly Otzman, a Sony spokeswoman, said in an e-mail just now:
"It's (Sony Computer Entertainment America) policy not to disclose our unit sales numbers until NPD numbers are officially released which will be December 13th. However, I can assure you that Microsoft's estimates of our PS3 unit sales numbers are way off and they did not outsell PS3 2:1 during Black Friday week."
