The difference in November was about 800k between the 2 consoles. It would prove my suspicions fully if the Switch was above PS4 then....
I'm not using this argument to attack the Switch. I come from a position of owning one, and having lots of friends who own one. I can see the kind of people who are buying one. Quite a few people I know, I figured were gone from the gaming cycle after going from WIi to phone/tablet gaming. It's nice to see none gamers come back. I hope that doesn't mean a tonne of shovelware party games every month.
No attacks, just a growing feeling that Amazon's predictive powers have been gazumped by the Switch. I simply think Amazon shows about 20% of Nintendo's sales. With PS4/XB1 about 6-8%, and Software maybe a little higher.
Again, November is driven by black friday sales which is mainly bought in stores and not on amazon.
