No need to quote some random website. Just use some common sense here.
Nintendo knows how many systems they have sold at any launch previous to the Switch. The easy way to ensure your new system sells more than any other launch is to manufacture way more than the other launches and tell tales of sold out pre sells. People will assue that this will be the same as all other launches of game systems and the new system will be hard to get. They will line up to get whatever you manufacture.
So, exceeding any previous launch is almost completely up to Nintendo to decide on. Why launch in March? Because they did the math and they wouldn't have enough systems made to even keep them instock for Nov 2016, let alone March this year. So, delay the launch from Nov 2016 to March 2017 and you can break all the nintendo sales records you want. No software was probably another problem, but obviously not a big enough one to stop launching now versus 3-6 months from now.
So, the sales numbers are literally manufactured to beat all previous launches...
Nintendo can't afford to not have "the best launch ever" after the wiiU. Give them credit for using some common sense.
It is near the end of the end....
