I assume that the system will still be very hard to get on release. Nintendo is going to hoard systems until November and flood the market until December. If you or I cannot get the system on release day, we will complain to other fans, but we will keep looking until we find one or break down and pay scalper prices.
On the other hand, parents will want to go to Walmart at 3 PM on Black Friday and grab a system. If they don't find one, they will be super mad that they have to explain to little Timmy that he is not getting a new Nintendo for Christmas. It will make the news.
What I would like to see is Nintendo limiting how much their resale partners can bundle with the system. For a while with the Switch, you could find one in stores… assuming you also buy a GameStop carrying case, a GameStop controller, a set of gold audio cables, and 3 shovelware games for a premium price.
