Nah in 2-3 years time when the Series X is still the same price it was on release day, people will still be buying the Series S.
It seems that a lot of people on here are still expecting big price drops for these consoles when it's just not going to happen. Even the previous generation barely saw any price drops. A PS4 is still bloody $400 here in australia. By this stage of the previous generations the consoles were in the bargain bin. The Switch still hasn't either.
With manufacturing processes where they are now there's just no room for price drops without the next big breakthrough in silicon or its replacement.
