Assuming these numbers are about right, that puts combined PS4+XBO sales at over 2.9M, a new record for combined PS+Xbox sales, beating out the previous record of Nov. 2015 (2835k). The best November last gen was Nov. 2011, which saw combined PS3+360 sales of 2.6M; that month now ranks #3 for best November for combined PS+Xbox sales. It's also the second-best November for an Xbox system ever, bested only by the 360's 1688k from Nov. 2011 (which is itself still the #2 best November performance ever behind only the Wii's showing in Nov. 2008). It also about ties with the PS4's performance in Nov. 2015, which was the #1 November ever for any PlayStation system, and the third-best November ever for a home console, bested only by the Wii and 360.
Also, it's worth pointing out that of the list of the Top 15 best November performances ever in the U.S. is utterly dominated by the Wii, 360, PS4, & XBO. The only other system to show in the list was the PS2, with its 1.3M sold in Nov. 2002 putting it at #7 (it's second-best November is all the way down at #17). The 360 takes the #2, #6, and #11 positions for 2011, 2010, and 2012, respectively. Not only does this show how freakishly popular the Wii was, it also shows how important November has become in recent years for PlayStation & Xbox. Prior to 2011, November was a much smaller portion of overall Q4 sales for the two brands. 2011 was when we really started to see aggressive Black Friday promotions, notably the temporary price cuts that are now the norm. While it's hard to say if November's growing importance has come at the expense of December, there's no doubt that November has been on the rise.
This does not seem to be the case for Nintendo, who have seen their relative Nov.-to-Dec. ratios jump around all over the place. 2011 saw the Wii drop a lot less in November than in December, with the two months having the second-closest Nov.-Dec. gap for Nintendo of the past 20 years outside of the launch years for the GameCube and Wii U (it gets beat by 2008, which saw the Wii's best November followed by a December that wasn't much bigger (can't say for sure, but since there weren't any big BF deals that I'm aware of, stock was likely the culprit).
Which brings me to the Switch. So, maybe it didn't break a million like most thought it might (Amazon showed it very close to the others, meaning it was very over-represented there). But there were also no big BF deals for the Switch, either. In the absence of such deals, I'm inclined to think we'll see a more typically lopsided holiday in December's favor like we've seen for most Nintendo systems throughout the years. It would not surprise me in the least if the Switch sold at least 1.4M in December. ~770k is not a bad month compared to how other systems did in November their first full Q4.
And with that, I'll wait until we get some confirmation of actual numbers before I update my charts.
