Because it's now selling more? And is it that hard to use the word "you", especially when you use it in a sentence with words like "consecutive"?
Did you even read what I said? How can the PlayStation 3 be close to or ahead of the Xbox 360 in the UNITED STATES (which is what Brandogg said) when the Xbox 360 has been the best selling console in the United States for the last 29 months? In the 79 months that both Xbox 360 and PlayStation have been available, PS3 has outsold it 8 times (January 2008 by 39K, February 2008 by 26K, May 2008 by 20K, June 2008 by 186K due to a MGS4 bundle selling about 220K, July 2008 by 20K, September 2009 by 139K after a price cut, October 2009 by 71K, December 2009 by 50K). The other 69 months the 360 outsold the PS3 in the US.
The IDC report (I looked it up) was about shipped systems, not sold.
