I dont see the prices going down at all unless there was some sort of competition of another chip being made. Plus hacking newer switch models is in high demand, so combined that with Covid ppl will take advantage of those prices.
I do believe modchip prices will come down. Production cost is minimal, no more than $15/each. It's quite ridiculous that we've been paying $170 on aliexpress for them, but finally we're getting some other options (taobao, shopee) and we can now at least get OLED chips for just about $100 on aliexpress.
