Well, i read something along the lines "according to The NPD Group, which tracks video game sales in the United States. From its launch in March 2017 through November 2018, Nintendo Switch has sold more than 8.7 million units, outpacing U.S. sales of all other current-generation systems at the same point in their life cycles." So is NPD who's saying Switch outpaced every other gen console. I don't remember giving an special annoucement for that with PS4 or XBO, they only said these kind of things on the monthly NPD news.
So, i don't understand why now they say something like this mid month and why they're calling Switch "current generation system". And the fact that they know the period of sales are not the same for Switch against PS4/XBO is not cited, so when in 3 months PS4 is still ahead of Switch, there will be no annoucemnt of Switch falling behind again, but this PR will remain in the conciousness of the people so people will think Switch is always ahead. If Nintendo was saying this it would be perfectly normal because is its best interest, but NPD should serve as impartial information of gaming sales, not for half truth news that only benfits one side....
It's pretty straight forward. How you possibly think this is some sort of conspiracy, I dont know.
