I think you are confusing a lack of supply for "killing the hype." While there are a few purchases that will probably never be made because of the shortages - the reality is that with Nintendo consoles, the appeal of them is so unique that the only choice you have if you want that experience is to buy the console. It doesn't matter if it's now or later, the hype hasn't died down. Most people will simply buy one when they can get one, and hell there's probably a lot of people that will buy the Switch the moment they see one just because it's so rare, no matter how much they actually want it.
But I don't think it will do what PS4 will do at the end of it's life, not because of shortages really ....
