According to an article by Jez Cordon in Windows Central, Sony & MS each sold around 1 million consoles in November, with Sony taking the lead by about 100,000 units overall.
The rumor that the information was provided to Jez by Crapgamer & some guy who calls himself Mooch, was refuted by Jez on Twitter when he was asked the question directly. You can see his response on his Twitter @jezcordon
Furthermore, there has been an edit posted on the article from the editor of Windows Central that reads as follows;
"Editor's Note: Due to the controversial nature of this article and the sourcing, I want to go on record as saying that the information provided here is 100% accurate and not something rumored. These are the facts for the November NPD figures and they have been vetted. -DR"
So take this information as you will, but according to the guys at Windows Central, their information is accurate.
