The thing is Thursday before Black Friday to the end of Cyber Monday been 5 days Is for sure a bigger sales period than the 800k that was done Sunday before to the Saturday after to the extent that the Sunday-Wednesday of the Wii tracking likely accounts for very little of the Wii's 800K, When you combine this along with knowing it's up 115% from the same 5 days in 2017 it already takes it above 800k for the same 5 day period. That you can't ignore.
Not for something with a very finite amount of stock, which previous popular Nintendo home consoles (like the Wii) would have. Those sell out quick so that there isn't anything to sell on Sat/Sun/Mon. The spin is obvious.
