Get it manufactured in China, Do some business investment magic, economy of scale things. I dont know :D It is really cool keyboard, but price is above of what most people are willing to pay for a keyboard.
By the way, another use-case is using it with games with complex controls like Elite Dangerous, Star Citizen, Kerbal Space Program.
First, they're partnered with Foxconn so it's very likely they're made in China.
Second, you can't just "do economies of scale" without a slightly pricier v1 of the product; hey're not going to be selling hundreds of thousands of them.
Third, many are more than willing to to pay over that amount for keyboard.
Just take a look at custom mechanical keyboards (Ergodox, Poker 3, k95 if you're looking at more mainstream ones) if you want a glimpse at the high-end keyboard market. I'm guessing that the "patented crisp, responsive key mechanism" are not mechanical switches, but people do (as do I) pay well over that for keyboards they're interested in.
The MOQ is 300k units; we're at economies of scale but it's still a new technology. You're right on the made in China, Suzhou, Shenzhen etc. Bingo also on the third point.
In regards to the fibre cabre, that's PR speak for a non cheap cable. Thanks again for the feedback; it's great to hear from other engineers etc.
