The costs have come down enough for a price drop period.
Anybody can make up stuff like no console drops 100 anymore unless they drop stuff lol.
Sales and costs coming down are what cause price drops.
With sales being the main reason.
Anyone can make up that a console comes down $100 in cost in a year too, see how that works? If you think it's $100 cheaper in one year you are mistaken and that's all there is to it.
