Interesting. PS4 was definitely the best selling console on Amazon; the daily and weekly charts bear that out. But perhaps even in online sales Amazon isn't big enough to be the main determinant of sales rank. I have no idea about methodology so it's hard to know how accurate this is, and there's no indication of size of difference or margin for error.
In some respects Amazon is the only sales tracker with 100% accuracy, for Amazon sales only of course.
I suspect that the only national data that has high reliability is NPD, and I wonder if NPD will make mention of BF performance, or if it will just stick to announcing top sellers for the month only.
Normally I would expect the BF winner = November NPD winner, but with Pro I guess that is unlikely to be true. Would make it a close month though.
